Find the probability left or right of a number

Probability to the left or right of a number, inclusive or not. prob_left() is a more general cdf defined using either < or <=, and prob_right() is a more general survival function defined using either > or >=.

Usage

prob_left(distribution, of, inclusive)

prob_right(distribution, of, inclusive)

Arguments

distribution

Distribution to find probabilities of.

of

Find the probability to the left or right of this number. Could be a vector.

inclusive

Should of be included in the probability calculation? Logical.

Value

A vector of probabilities.

Examples

d <- dst_pois(5)
prob_left(d, of = 3, inclusive = TRUE)
#> [1] 0.2650259
prob_left(d, of = 3, inclusive = FALSE)
#> [1] 0.124652
prob_right(d, of = 0:3, inclusive = TRUE)
#> [1] 1.0000000 0.9932621 0.9595723 0.8753480
