Sir I have this problem,> res <-maxLik(logLik=loglik1,start=c(a=1.5,b=1.5,c=1.5,dee=2),method="BFGS") There were 50 or more warnings (use warnings() to see the first 50)> summary(res)"Maximum Likelihood estimation BFGS maximisation, 0 iterations Return code 100: Initial value out of range." Dear sir how we give the initial value to estimate the parameters. Reg, Farrukh [[alternative HTML version deleted]]
