Grid search parameters in proc GLIMMIX

mgx — Wed, 06 Apr 2022 14:44:43 GMT

I want to specify a range of parameters in PROC GLIMMIX for several parameters, but not for others. How can I code this? I want to specify a grid search to a range of parameters for the values that are in my code below initially set to 0. My code looks like this:

proc glimmix data=dataset method=quad(qpoints=10) initglm;
parms 
(0.7680)
(-5.4775) (39.5841)
(0) (0) (20.5296)
(0) (0)(-146.07) (1046.48);
nloptions maxfunc=10000 maxiter=10000 gconv=1e-8 fconv=1e-8 technique=newrap;
class var surveyid distvar linkvar;
model response = var var*time var*gender/noint dist=byobs(distvar) link=byobs(linkvar) covb solution;
random int1 slope1 int2 slope2/type=un subject=ID ;
run;

Thank you in advance!

You can specify a grid search by listing multiple initial values in the PARMS statement for one parameter, for example,

parms 
(0.7680)
(-5.4775) (39.5841)
(0.4 2) (-2 to 2 by 1) (20.5296)
(0) (0)(-146.07) (1046.48);

Here is more information in the documentation --
