Zeta and Zipf distribution
Dear R user,
I want to estimate the parameter of ZETA or/and ZIPF distributions
using R, given a series of integer values. Do you know a package
(similar to MASS) or a function (similar to fitdistr) I can use to
estimate the parameter of these distributions using MLE method?
Otherwise do you know a function (which use MLE method to estimate
distribution parameters) that allow me to specify a

Integrate inside function
Dear R users,
first I take this opportunity to greet all the R community for your
continuous efforts.
I wrote a function to calculate the pdf and cdf of a custom distribution
(mixed gamma model).
The function is the following:
pmixedgamma3 <- function(y, shape1, rate1, shape2, rate2, prev)
{
density.function<-function(x)
{
shape1=shape1
rate1=rate1
shape2=shape2

qda(MASS) function error
Dear R user,
I'm using qda (quadratic discriminant analysis) function (package
MASS) to classify 58 explanatory variables (numeric type with different
ranges) using a grouping variable (factor 2 levels "0" "1"). I'm using
the qda method for class 'data.frame' (in this way I don't need to
specify a formula).
Using the function:
