Dear list. I am student M.S. statistics in department statistics .I have thise problem in work with the function variofit and nls and dont know how to solve it. var1<-variog(data,option="bin") var2<-variog(data,option="cloud") v1<-var1$v u1<-var1^u v2<-var2$v u2<-var2$u variofit(var1,ini.cov.pars

Re: [R] please help me

You need better starting values: f <- function(x) { c0 <- x[1]; ce <- x[2]; ae <- x[3] sum((v - c0+(ce*(1-exp((-u)/ae^2) } g <- 4^(0:8) g <- c(-g, g) g <- expand.grid(c0 = g, ce = g, ae = g) start <- g[which.min(apply(g, 1, f)), ] nls(v ~ c0+(ce*(1-exp((-u)/ae))), data = data1, start = star
