function in nls argument
...qnum <- quantile(abserr, probs=0.95, na.rm=T)
is.na(abserr) <- (abserr > qnum)
errsq <- sum(abserr^2, na.rm=T)
errsq
}
Then I want to optimize parameters a,b,d and E as to
minimize the function output with the following:
optim.model<-nls(nulldat ~ optim.fun(ST04, SM08b,
ch2no, a, b, d, E), data=tower,
start=list(a=-0.003,b=0.13,d=0.50, E=400), na.action =
na.exclude )
were nulldat=0
At this point I get the following error message:
Error in qr.default(.swts * attr(rhs, "gradient")) :
