2.14 The Poisson Distribution

# family of distributions parameterized by lambda ("mean rate")
poisson_values <- rpois(n = 10000, lambda = 5)

hist(poisson_values, breaks = 30)

# normalize distribution for QQ
poisson_values <- (poisson_values - mean(poisson_values))/sd(poisson_values)
qqnorm(poisson_values); qqline(poisson_values, col = 2)
