Hi: Could you please guide me how to do a qq plot for a 3-parameter lognormal curve. Here is an example from VGAM package to fit lognormal curve. I need to do a qq plot to check the fit. Thanks.
lambda = 4 y = lambda + rlnorm(n <- 1000, mean=1.5, sd=exp(-0.8)) fit = vglm(y ~ 1, lognormal3, trace=TRUE) Coef(fit) summary(fit) reez __________________________________________________________________ [[elided Yahoo spam]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
