smovie 1.1.1

New features

  • New movie: cltq(). Central Limit Theorem for sample quantiles. Illustrates the sampling distribution of the sample quantiles and the central limit theorem for sample quantiles.

  • New movie: mean_vs_median(). Compares the sampling distributions of the mean and median for random samples from either a standard normal distribution or a standard Student t distribution.

  • pkgdown documentation at https://paulnorthrop.github.io/smovie/

Bug fixes and minor improvements

  • In ett() the sample size n is now allowed to drop to 1 for those cases in which the normalising constants underlying the calculations are finite, such as the exponential, uniform and generalised Pareto distributions. Otherwise, 2 is the smallest allowable value for n.

  • When the Wald, Wilks and Score tests movie wws() is called from the main menu, via movies() a binomial example is used, so that the differences between the test statistics can be seen.

  • Adjustments have been made to the wws() movie to ensure that the plot stays completely still during the animations.
