I constructed a likelihood function and then use optim to slove the mle. It
gave the error like:
> LBCE.est<-optim(c(2,2,1),LBCE,hessian=T)
Error in integrate(LBCE.fc.4.1, lower = 0, upper = Inf) :
the integral is probably divergent
However, when I checked the the function of LBCE.fc.4.1, it can generante
values with various pamameters.
> LBCE.fc.4<-integrate(LBCE.fc.4.1,lower=0,upper=Inf)$value
> LBCE.fc.4
[1] 1.047198
don't know how to check the error and solve the problem.
Please help me !
