### Some Movies to
Illustrate Concepts in Statistics

### What does smovie do?

The `smovie`

package provides movies to help students to
understand statistical concepts. The `rpanel`

package is used to create interactive plots that move to illustrate
key statistical ideas and methods. The movies cover the topics of
probability distributions; sampling distributions of the mean (central
limit theorem), the median, the maximum (extremal types theorem) and the
(Fisher transformation of the) correlation coefficient; simple linear
regression; hypothesis testing.

### An example

The function `wws`

produces a movie to visualise the Wald,
Wilks and score likelihood-based test statistics, for a model with a
scalar unknown parameter. The user can change the value of the parameter
under a simple null hypothesis and observe the effect on the test
statistics. The following code uses the log-likelihood from a binomial
experiment and considers the null hypothesis that the success
probability *θ* is equal to *θ*_{0}. The user may
specify their own log-likelihood.

### Installation

To get the current released version from CRAN:

`install.packages("smovie")`

### Vignettes
