Dear R users,
Does anyone know of a package that implements the Johnson-Neyman procedure -
for testing differences among groups when the regression slopes are
heterogeneous (in an ANCOVA model)? I did not get any matches for functions
when searching using R Site Search.
If it has not been implemented in R, does anyone know of another statistical
package that has this procedure? I found very old scripts available for
Mathematica, but have had difficulty getting them to work.
Thanks in advance.
