Draw many random samples and compute confidence interval. How many
intervals capture the true mean?
Usage
confIntDemo(distr = "normal", size = 20, conf.level = 0.95)
Arguments
- distr
distribution of the population to be sampled. Options include
"normal", "exponential", "uniform" and "binary"
(partial match allowed).
- size
sample size
- conf.level
confidence level.
Value
The command invisibly returns the fraction of intervals that capture
the true mean.
Details
This simulation will draw 100 random samples from a given population
distribution and compute the correpsonding confidence intervals. The 100
intervals will be drawn with an indication of the ones that missed the true
mean. A histogram of the population will also be created.
Examples
confIntDemo()
confIntDemo(distr = "exponential", size = 40)
