Quantiles by Group calculation in R, Quantiles are numbers in statistics that divide a ranking dataset into equal groups. In R, we can use the following functions from the dplyr package to calculate quantiles grouped by a certain variable. library(dplyr) Identify the quantiles that you’re interested in. q<-c(0.25, 0.5, 0.80) Quantiles are calculated by grouping…

Multinomial Distribution in R, when each result has a given probability of occurring, the multinomial distribution describes the likelihood of obtaining a specific number of counts for k different outcomes. A statistical experiment with n repeated trials is known as a multinomial experiment. There are a finite number of possible outcomes in each trial. The…
