smovie: some movies to illustrate concepts in statistics

These movies are animations used to illustrate key statistical ideas. They are produced using the rpanel package.

Details

When one of these functions is called R opens up a small parameter window containing clickable buttons that can be used to change parameters underlying the plot. For the effects of these buttons see the documentation of the individual functions.

See vignette("smovie-vignette", package = "smovie") for an overview of the package and the user-friendly menu panel.

There are movies on the following topics.

Probability distributions

• Discrete distributions

• Continuous distributions

Sampling distributions

• Central Limit Theorem: sampling distribution of a sample mean

• Central Limit Theorem for sample quantiles: sampling distribution of the 100p% sample quantile

• Sampling distributions of the mean and median

• Extremal Types Theorem: sampling distribution of a sample maximum

• Correlation coefficient

Regression

• Leverage and influence in simple linear regression

Hypothesis testing

• Wald, Wilks and Score tests

• Testing simple hypotheses
