### 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](https://cran.r-project.org/package=rpanel) 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 $\theta$ is equal to $\theta_0$.  The user may specify their own log-likelihood.

```{r, eval = FALSE}

wws(theta0 = 0.5)

```

### Installation

To get the current released version from CRAN:

```{r installation, eval = FALSE}

install.packages("smovie")

```

### Vignettes

See `vignette("smovie-vignette", package = "smovie")` for an overview of the 

package.
