st: fractional polynomial with glm and the cluster option

[Garry Anderson <g.anderson@unimelb.edu.au>]

Hi,

mfp is multivariable fractional polynomial.

I am wishing to do
mfp glm y x , fam(nb #) link(log) cl(cluster)

The message -option cl() not allowed- appears

The mfp command is not allowed with nbreg.

-mfp poisson y x,cl(cluster)- does produce results
-mfp glm y x,fam(poisson)- does produce results
-glm y x,fam(poisson) cl(cluster)- does produce results
-mfp glm y x,fam(poisson) cl(cluster)
    produces the message -option cl() not allowed-
Therefore the cluster option with -mfp glm y x,cl(cluster)- is producing 
the message.
The help file for mfp indicates that
"regression_cmd_options may be any of the options appropriate to 
regression_cmd."

The same applies to the fracpoly command.

Any ideas would be appreciated as to why the cluster option does not work 
with -glm-, but does work with -poisson-

Regards, Garry
