Inclusion Probabilities: Complete Random Sampling

complete_rs_probabilities(N, n = NULL, n_unit = NULL, prob = NULL,
prob_unit = NULL, check_inputs = TRUE)

## Arguments

N The number of units. N must be a positive integer. (required) Use for a design in which exactly n units are sampled. (optional) unique(n_unit) will be passed to n. Must be the same for all units (optional) Use for a design in which either floor(N*prob) or ceiling(N*prob) units are sampled. The probability of being sampled is exactly prob because with probability 1-prob, floor(N*prob) units will be sampled and with probability prob, ceiling(N*prob) units will be sampled. prob must be a real number between 0 and 1 inclusive. (optional) unique(prob_unit) will be passed to the prob argument and must be the same for all units. logical. Defaults to TRUE.

## Value

A vector length N indicating the probability of being sampled.

## Examples

probs <- complete_rs_probabilities(N = 100) table(probs)
#> probs #> 0.5 #> 100
probs <- complete_rs_probabilities(N = 100, n = 50) table(probs)
#> probs #> 0.5 #> 100
probs <- complete_rs_probabilities(N=100, prob = .3) table(probs)
#> probs #> 0.3 #> 100
