 Main Menu return to Main Menu Insurance Experiment This program shows how the variability of casualty policy experience creates a problem for small insurance companies. Law of Averages the convergence of means the 'law of averages'. Simulated Regression This program is one that an instructor could use to introduce simple linear regression. Smoothing Time Series Example This R module demonstrates with real data that gas consumption as usually measured by drivers is quite variable, and with no apparent trend, until a nonparametric smoother reveals a very distinct seasonal pattern. Sampling Distribution of the Sample Mean illustrates the sampling distribution of the sample mean Investment Diversification illustration about portfolio diversivication and its relationship with de standard deviation of sample means
