ppois()
function in R Language is used to compute the cumulative density function for Poisson distribution.
Syntax: ppois(vec, lambda)
Parameters:
vec: Sequence of integer values
lambda: Average number of events per interval
Example 1:
# R program to compute # Cumulative Poisson Density # Sequence of x-values x < - seq( - 10 , 10 , by = 1 )
# Calling ppois() Function y < - ppois(x, lambda = 5 )
y |
