Generate data for a 2-by-3 design and use the function pbad2way. Note the contrast coefficients for interactions. If you again use pbad2way, but with conall=F, what will happen to these contrast coefficients? Describe the relative merits of using conall=T

For the schizophrenia data in Section 7.8.4, compare the groups with t1way and pbadepth.
