Flexmix package

[kimk]

Hi,

I am using the package "flexmix" and would like get some assistance.

I am trying to run two equations jointly
Y1=X1B+E1
Y2=X2G+E2

So that I have X and Y in a matrix format and would like to run the latent class model using flexmix.
Though, my problem here is that Flexmix automatically generates intercepts.
I have intercept for both of the equations that my X matrix looks like this...
1 X11 X21  X31   0   0   0   0
:     :     :      :    0   0   0   0
0    0     0     0   1  X21 X22 X23
0    0     0     0   :     :     :      :  
Here, I would like to specify that it doesn't generate the intercepts automatically and run this data directly.

Any advice would be helpful. Thank you!
