Вычисление отрицательной биномиальной плотности в программировании на R - функция dnbinom ()
Опубликовано: 17 Февраля, 2022
dnbinom() function in R Language is used to compute the value of negative binomial density. It also creates a plot of the negative binomial density.
Syntax: dnbinom(vec, size, prob)
Parameters:
vec: x-values for binomial density
size: Number of trials
prob: Probability
Example 1:
# R program to compute# Negative Binomial Density # Vector of x-valuesx <- seq(0, 10, by = 1) # Calling dnbinom() Functiony <- dnbinom(x, size = 10, prob = 0.5)y |
