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

Dear R helpers   I have some files in my say 'WORK' directory and the file names are say rate1.csv, rate2.csv, rate3.csv, rate4.csv   Because of some other requirement, I need to run the following commands   n = 4    rates = NULL   for (i in 1:n) rates[i] = (paste(`rate', i, ‘.csv`, sep = ‘’))   # this gives me "rate1.csv" "rate2.csv" and so on   #My problem is

Hi, I am trying to implement a simple scaled-down version of the AF traffic class type. As such I basically want to remark non-conforming AF11 packets to AF13.

Dear All, I am trying to do some simple mixture analyses. For instance, I have a sample of n observations and I suspect they come from two different exponential distributions with parameters rate1 and rate2, respectively. So, I want to estimate rate1, rate2, and the proportions of both kinds of individuals in the sample. I had a look at the packages mda and mclust, but they do not seem to do this

My mistake sir. I was literally engrossed in my stupid logic, and while doing so, overlooked the simple and very effective solution you had offered. Sorry once again sir and will certainly try to be very careful in future. Thanks again and have a great weekend sir.
