Arguments

thetah	(nparm) space for thetahat
theta	(nparm) true value of theta
xnew	hold space for x
ynew	hold space for y
centim	(nsubex) vector of censor times for alt
acvar	(nsubex,nacvar) matrix of accelerating vars
nsubex	number of subexperiments
nacvar	number of accelerating variables
nsamsz	(nsubex) vector giving number of units at each comb
kctype	= 1 for type 1 at centim, = 2 for type 2 with centim failures
retmat	(numret,numsim) matrix to return results, one result per col
numsim	number of simulations to be run
iersim	> 0 if data space too small
Accelerating	Variable - X1, X1, Comb1, Comb2, Comb3
nrowr	number of rows being returned in retmat

Parameter meanings same as in wqm_mlboth except those listed here

Note

Modified 19 December 1997 to account for multiple accelerating variables
