Population vs Sample Regression

This app shows the difference between the population and sample regression lines.

Minimisation of SSR: The guess

In this app, you can play to guess what the line is that minimises the sum of squared residuals.

Minimisation of SSR: The guts

This app takes you through the process of minimising the sum of squared residuals.

Beta Distributions

This app shows what happens to the distribution when the sample size or the number of simulations gets arbitrarily large.

Generalised Least Squares

Under heteroskedasticity, what is the gain in precision when we consider GLS instead of OLS?
