[mathjax] Learning Objectives After completing this case study, you should be able to: Fit a multiple linear regression model with both numeric and categorical (factor) predictors. Detect and accommodate interactions between predictors which can be quantitative or qualitative. Perform explicit binarization of categorical predictors using the dummyVars() function from the caret package and understand why doing so may be beneficial. …
[mathjax] Context Suppose that we are statistical consultants hired by the company that offers the product. The company is interested in boosting sales of the product, but cannot directly do so (that is determined by market demand). Instead, it has the liberty to control the advertising expenditure in each of the three advertising media: TV, radio, and newspaper. If we …
[mathjax] Basic Terminology Classification of Variables There are two ways to classify variables in a predictive analytic context: By their role in the study (intended use) or by their nature (characteristics). By role The variable that we are interested in predicting is called the target variable (or response variable, dependent variable, output variable). The variables that are used to predict …

Module Overview Module Introduction Many government and quasi-government agencies regulate life insurance companies. They exercise authority over both the life insurance industry and the individual companies. Regulation and taxation affect product design—sometimes by incentive and sometimes by required standards. For example, the states in the United States have laws that govern solvency of companies and also often levy state premium …

Product Classification Why need product classification? Not all products manufactured by insurance companies are insurance contracts Insurance contracts are those that contain significant insurance risk How products are classified? For valuation purposes, insurance contracts can be further classified into: Ordinary Life – Participating Ordinary Life – Non-Participating Personal Accident Unit-linked (Contracts with an explicit account balance) Universal life (Contracts with …
Introduction IFRS 17 Insurance Contracts establishes principles for the recognition, measurement, presentation and disclosure of insurance contracts issued. It also requires similar principles to be applied to reinsurance contracts held and investment contracts with discretionary participation features issued. The objective is to ensure that entities provide relevant information in a way that faithfully represents those contracts. This information gives a …

Function Categories The Prophet programming language provides a wide range of functions which are grouped into the following categories: Array functions Conversion functions Dynamic functions Error / Warning functions Financial functions Logical functions Mathematical functions Product functions Read functions Run Position functions Run Progress functions Run Setting functions Statistical functions Text functions Trigonometric functions Array Functions Function Description ARRAY_INITIALISE Resizes …
Extended formulas enable more complex calculations to be carried out than standard Prophet formulas. They are also able to retain the values that they have calculated from one model point to the next and from one loop to the next in a dynamic or stochastic run. Examples of situations where extended formulas can be useful include: The calculation of commutation …
Overview The Prophet programming language is the programming language used to create and maintain formula definitions for variables in each product and library. A formula in Prophet can be specified using either: The standard Prophet language features or, The Prophet Extended Formula features. A formula created using the standard Prophet language generates values for one variable only. An extended formula …
Purpose Extended formulas enhance and extend the capabilities of the Prophet programming language. They enable more complex calculations to be carried out than standard Prophet formulas. They are also able to retain the values that they have calculated from one model point to the next and from one loop to the next in a dynamic or stochastic run. Examples of …
