# Mathematical Actuarial StatisticsExam PCT3CS1

By MJ the Fellow Actuary 4.1/5

## Mathematical Actuarial StatisticsExam PCT3CS1

### What you’ll learn

A solid understanding of statistics and a good foundation of models, correlation and hypothesis testing. ### Requirements

Must be comfortable with Maths and patient as these concepts can be tricky.

### Description

Statistics is all about processing data and extracting information. The information we seek is the parameters and distribution of the random variable that generated the data. Armed with this information we can answer questions about reality and optimize industrial processes. Statistics thus forms the backbone of science and business and this course is designed to help you understand the components of this fundamental subject and how they all fit together. Designed for Actuaries, but applicable for everyone. This course contains the new sections for the CS1 exam.Sections:Exploratory Data AnalysisGeneral Probability TheoryRandom VariablesProbability DistributionsGenerating FunctionsJoint Distributions (Covariance)Conditional ExpectationsCentral Limit TheoremSampling and Statistical InferencePoint EstimationConfidence IntervalsHypothesis TestingLinear Regression and CorrelationAnalysis of VarianceBayesian Statistics and Credibility TheoryStudent QuestionsIntroduction to R Programming
