norm2ordinal

Transforms a vector with a normal distribution to a binomial distribution with two values.

Power analysis for regression models which test the interaction of
two independent variables on a single dependent variable. Includes options
for continuous, binary, or ordinal variables, as well as correlated
interacting variables. Also includes options to specify variable reliability.
Power analyses can be done either analytically or via simulation. Includes
tools for simulating single data sets and visualizing power analysis results.
The primary functions are power_interaction_r2() and power_interaction().
