Compute the Value of Poisson Density in R Programming – dpois() Function
dpois() function in R Language is used to compute the Poisson Density for a set of Integer values. It also creates a density plot of poisson distribution.
Syntax: dpois(vec, lambda)
Parameters:
vec: Sequence of integer values
lambda: Average number of events per interval
Example 1:
Python3
x < - seq( - 10 , 10 , by = 1 )
y < - dpois(x, lambda = 5 )
y
