The function sampvals generates the data. A density plot of a normal probability plot is provided, for one or mare sample sizes. For a density plot, the density estimate for the population is superimposed in gray. For the normal probability plot, the population plot is a dashed gray line. Default arguments give the sampling distribution of the mean, for a distribution that is mildly positively skewed.

CVbinary
(Package: DAAG) :
Cross-Validation for Regression with a Binary Response
These functions give training (internal) and cross-validation measures of predictive accuracy for regression with a binary response. The data are randomly divided between a number of ‘folds’. Each fold is removed, in turn, while the remaining data are used to re-fit the regression model and to predict at the omitted observations.

onesamp
(Package: DAAG) :
Paired Sample t-test
This function performs a t-test for the mean difference for paired data, and produces a scatterplot of one column against the other column, showing whether there was any benefit to using the paired design.
