“Actuarial science is the discipline that applies mathematical and statistical methods to assess risk in insurance, finance and other industries and professions ”. There is a natural division between fundamental actuarial concepts, the foundations which must be mastered to enter the actuarial profes- sion, and standards. in working in actuarial sciences, in insurance and in finance can improve research on these topics. With the pdf function it is possible to construct a maximum.

A parametric cumulative distribution function is initially used to transform the data into values over the unit interval, from which a nonparametric density estimation is obtained. Finally, an estimation of the density of the original sample is obtained by back-transformation. This approach may be particularly useful to estimate heavy-tailed distributions. We discuss its implementation and its finite sample properties for density estimation, and for estimation and inference with quantiles. More specifically, I will examine connections between the two, derive the underlying dependencies formally and explore the implications, state characteristic results and touch on some well-known special cases, formulate admissible classes of distributions of the r. I will conclude with a number of applications to actuarial pricing and risk measurement. While aggregation of several risky assets generally reduces the overall investment risk, the effectiveness of diversification depends on the stochastic properties of the assets comprising the portfolio.

The original subjects for the examination were arithmetic, algebra, probability, compound interest, life contingencies assurances and annuities , mortality tables see Life Table , and bookkeeping.

By , the requirements were to sit for three examinations over three years. A course of reading and syllabus was prescribed but otherwise students were left to study on their own.

In , Sutton was appointed as the first tutor to the Institute with 10 students. Edward Sang wrote some scientific papers and gave his first course of actuarial lectures in He must be one of the first actuaries to make his living from academic and consulting activities.

As with the Institute, entry to the profession was in the hands of the profession and was by examination. The first actuarial textbooks sponsored by the profession appeared in Part 1 — annuities — by Sutton and Part 2 — life annuities and assurances by King. Admission to the professional ranks of the actuarial profession in the United Kingdom as Fellow of the Faculty or Institute was from the start, and continues to be, by examination conducted by these two professional bodies.

Syllabuses, courses of reading, and tuition material were supplied, but it was up to the student to study in his spare time. It was not necessary to have attended a university and many future actuaries entered life offices straight from school. An Actuarial Education Service tuition by correspondence course was set up in the United Kingdom in The passing of these examinations, resulting in full membership Fellowship of the professional body, conferred on actuaries in these countries, the same professional status as lawyers and doctors.

General insurance was not part of the UK actuarial education until In North America, although the universities play an important part in actuarial education, no exemptions from parts of the actuarial examinations are or were in the past given for university examinations. The departments of actuarial mathematics are situated, in some universities, in the mathematics department and in others, in the economics department.

Anyone from a previously disadvantaged background can join EDU. Yes, but not from UCT. The exemptions can only be granted by the university where the relevant courses were completed. If I was asked to leave the Actuarial Science stream can I return? Yes, you can redo the relevant Mathematics and Statistics courses and apply to return to the stream given you have attained the marks required for entrance to Financial Mathematics. Acceptance will be at discretion of the HOD.

How do I know I am registered for the courses I signed up for? It is your responsibility to ensure that you are registered for the correct courses on Peoplesoft.

This needs to be done within a week of registration. Do I have to pay fees for a course I have registered for but no longer want to do? If you de-register for a course within the first week of lectures, you are not charged for the course.

After the first Friday of lectures, certain penalties will apply.

Certain aspects of the actuarial methods for discounting pension funds have come under criticism from modern financial economics. In traditional life insurance, actuarial science focuses on the analysis of mortality , the production of life tables , and the application of compound interest to produce life insurance, annuities and endowment policies.

Contemporary life insurance programs have been extended to include credit and mortgage insurance, key person insurance for small businesses, long term care insurance and health savings accounts Hsiao In health insurance, including insurance provided directly by employers, and social insurance, actuarial science focuses on the analysis of rates of disability, morbidity, mortality, fertility and other contingencies.

The effects of consumer choice and the geographical distribution of the utilization of medical services and procedures, and the utilization of drugs and therapies, is also of great importance. Actuarial science also aids in the design of benefit structures, reimbursement standards, and the effects of proposed government standards on the cost of healthcare CHBRP In the pension industry, actuarial methods are used to measure the costs of alternative strategies with regard to the design, funding, accounting, administration, and maintenance or redesign of pension plans.

The strategies are greatly influenced by short-term and long-term bond rates, the funded status of the pension and benefit arrangements, collective bargaining ; the employer's old, new and foreign competitors; the changing demographics of the workforce; changes in the internal revenue code; changes in the attitude of the internal revenue service regarding the calculation of surpluses; and equally importantly, both the short and long term financial and economic trends.

It is common with mergers and acquisitions that several pension plans have to be combined or at least administered on an equitable basis.

When benefit changes occur, old and new benefit plans have to be blended, satisfying new social demands and various government discrimination test calculations, and providing employees and retirees with understandable choices and transition paths.

Benefit plans liabilities have to be properly valued, reflecting both earned benefits for past service, and the benefits for future service. Finally, funding schemes have to be developed that are manageable and satisfy the standards board or regulators of the appropriate country, such as the Financial Accounting Standards Board in the United States.

In social welfare programs, the Office of the Chief Actuary OCACT , Social Security Administration plans and directs a program of actuarial estimates and analyses relating to SSA-administered retirement, survivors and disability insurance programs and to proposed changes in those programs. It evaluates operations of the Federal Old-Age and Survivors Insurance Trust Fund and the Federal Disability Insurance Trust Fund, conducts studies of program financing, performs actuarial and demographic research on social insurance and related program issues involving mortality, morbidity, utilization, retirement, disability, survivorship, marriage, unemployment, poverty, old age, families with children, etc.

## Introduction to Actuarial Science

In addition, the Office is charged with conducting cost analyses relating to the Supplemental Security Income SSI program, a general-revenue financed, means-tested program for low-income aged, blind and disabled people.

The Office provides technical and consultative services to the Commissioner, to the Board of Trustees of the Social Security Trust Funds, and its staff appears before Congressional Committees to provide expert testimony on the actuarial aspects of Social Security issues.

Applied to other forms of insurance[ edit ] Actuarial science is also applied to property , casualty , liability , and general insurance. In these forms of insurance, coverage is generally provided on a renewable period, such as a yearly. Coverage can be cancelled at the end of the period by either party. Property and casualty insurance companies tend to specialize because of the complexity and diversity of risks. Personal lines of insurance are for individuals and include fire, auto, homeowners, theft and umbrella coverages.

The insurance industry also provides coverage for exposures such as catastrophe, weather-related risks, earthquakes, patent infringement and other forms of corporate espionage, terrorism, and "one-of-a-kind" e.

Actuarial science provides data collection, measurement, estimating, forecasting, and valuation tools to provide financial and underwriting data for management to assess marketing opportunities and the nature of the risks. Actuarial science often helps to assess the overall risk from catastrophic events in relation to its underwriting capacity or surplus.

In the reinsurance fields, actuarial science can be used to design and price reinsurance and retrocession arrangements, and to establish reserve funds for known claims and future claims and catastrophes.
