Re: [R] Non-linear regression with latent variable

2009-05-21 Thread spencerg 
 If you have the RSiteSearch package installed, you can do the 
following: 



library(RSiteSearch)
nrow(nll - RSiteSearch.function(nonlinear regression with latent))
HTML(nll)


 This just produced 8 hits for me.  If this doesn't solve your 
problem, you might  try other search terms.  If all those fail, you 
could write your own likelihood function and use the maxLik package. 



 Hope this helps.

Hi 
Can anyone please suggest me a package where I can estimate a non-linear

I have an indicator variable for this unobserved variable; however the
relationship is known to be non-linear also. In terms of equations my
problem is

y=f(latent, fixed) 
q=g(latent) where q is the indicator variable


For me both f and g are non-linear.

Thanks
