Hi Stata list, I am running the following regression y=a0+a1bt+a2bt*rt+a3bt*r^2t+a4btr^3t+et where t is the time subscript. Now I want to perform following conditional tests: a4=0 a3=0|a4=0 a2=0|a3=a4=0 First test is easy to implement in Stata with -test- command after regress. However, I need your help in implementing the remaining two commands. Any help will be greatly appreciated.
