normal_pdf_movie: Normal p.d.f. movie

In paulnorthrop/stat0002: Introduction to Probability and Statistics

Normal p.d.f. movie

Description

A movie to show how the probability density function (p.d.f.) of the normal distribution varies as the mean and/or variance of the distribution are changed. For more continuous distributions, including the exponential and uniform distributions, use smovie::movies() and click on the Continuous menu. This is based on the continuous function. (If you have not installed the smovie package then use install.packages("smovie") to install it.)

Usage

normal_pdf_movie(
  starting_mean = 0,
  starting_var = 1,
  delta_mean = 0.1,
  delta_var = 0.1
)

Arguments

starting_mean	A numeric scalar. The value of the mean used to produce the first plot of the p.d.f.
starting_var	A positive numeric scalar. The value of the variance used to produce the first plot of the p.d.f.
delta_mean	A numeric scalar. The amount by which the value of the mean is increased/decreased after one click of the +/- button for the mean.
delta_var	A numeric scalar. The amount by which the value of the variance is increased/decreased after one click of the +/- button for the variance.

Details

The values of the mean and/or variance can be changed using the +/- buttons in the panel. For the purposes of this movie, the variance cannot be reduced below a value of 0.1.

Value

Nothing is returned, only the animation is produced.
