Questions about changing im=2

[wyj970822]

Dear Kai，

Thanks for all the effort you have done to this package. Since I am new to this PSTR model, I have a question of specifying the number of the switches.

When I use the EstPSTR function, if I use im = 2, it would have the Error in cbind(de1, -tmp1 * tmp4 * gamma) :
dims [product 300] do not match the length of object [600] (my panel data is 10 years*30 individuals)

I am trying to compare the results of im = 1 and im = 2, can you explain this for me? Thank you very much!
