NormalQQPlot function

Normal Quantile Quantile Plot

Produces an emperical QQ-Plot of the quantiles of the data set 'Ra' versus the quantiles of a normal distribution. The purpose of the quantile-quantile plot is to determine whether the sample in 'Ra' is drawn from a normal (i.e., Gaussian) distribution.

NormalQQPlot(Ra)

Arguments

• Ra: Vector data set

Examples

# Normal QQ Plot for randomly generated standard normal data
   Ra <- rnorm(100)
