Zero-truncated Poisson probability function

pf_ztp(n, theta)

Arguments

n

Function support, with \(n = 1, 2, \cdots\).
theta

Theta parameter, such that \(\theta > 0\).

Value

Calculated probability (vector)

Examples

sapply(
   X = 1L:1000L,
   FUN = function(i)
   pf_ztp(n = i, theta = 1.2)
) %>% sum
