Dear R-users,
I am new to R and would like to use it for fitting the zipf distribution to
some numeric data that I have. Here's the snippet that I use:
library(VGAM)
X <- read.table(file("~\\mydata.txt", encoding="latin1"))
w <- as.vector(t((X[2])))
w <- w/sum(w)
y <- (1:length(w))
fit = vglm (y ~ 1, zipf, tra=TRUE, weight=w)
zipf(N=NULL, link="loge", earg=w, init.s=NULL)
coef(fit, matrix=FALSE)
Though R returns the necessary values, I am not entirely sure if this value
returned (by the last command),is log(s) or log(-s), where s is the zipf
exponent.
Any clarification would be greatly appreciated! Thank you in advance!
