Confidence interval simulation, enhanced ----------------------------------------cidemo2 samplesize , [ level( ) samples( )]
Description -----------
cidemo2 draws 100 random samples of size samplesize from a normal distribution.
By default 100 samples are drawn and a 95% confidence interval is computed for each of the 100 means. The results are displayed in an error bar graph.
Options --------
level( ) - the confidence level, default = 95% samples( ) - the number of samples to display, default = 100
You can create an animation showing how the confidence level impacts the size of the confidence interval by including more than one confidence levels in the level( ) option. For example, level(80 81 to 99) shows 20 consecutive graphs with confidence of 80%, 81%, 82% to 99%.
Examples --------
. cidemo2 25 . cidemo2 25, level(90) . cidemo2 25, samples(50) . cidemo2 25, level(99 98 to 90)
