- Probability Distributions: Familiarity with distributions such as normal, binomial, and Poisson is essential for modeling various scenarios.
- Statistical Inference: Techniques for drawing conclusions about populations based on sample data.
Financial Mathematics
Actuaries must grasp financial mathematics to evaluate cash flows, investments, and liabilities. Important concepts include:
- Time Value of Money: Understanding how the value of money changes over time due to interest rates and inflation.
- Discounting and Present Value: Calculating the present value of future cash flows is crucial for assessing liabilities.
- Annuities and Mortgages: Familiarity with different types of financial products and how they impact risk assessment.
Actuarial Models
Actuarial modeling involves creating mathematical representations of real-world processes to analyze risks. Common models include:
- Survival Models: Used to estimate the probability of a person surviving to a certain age or time.
- Loss Models: Help predict the frequency and severity of claims in insurance.
- Markov Models: Useful for modeling transitions between different states, such as health statuses.
