Description

Inclusion Probabilities: Complete Random Sampling

Usage

 ```1 2``` ```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) `n` Use for a design in which exactly n units are sampled. (optional) `n_unit` unique(n_unit) will be passed to `n`. Must be the same for all units (optional) `prob` 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) `prob_unit` unique(prob_unit) will be passed to the prob argument and must be the same for all units. `check_inputs` logical. Defaults to TRUE.

Value

A vector length N indicating the probability of being sampled.

Examples

 ```1 2 3 4 5 6 7 8``` ```probs <- complete_rs_probabilities(N = 100) table(probs) probs <- complete_rs_probabilities(N = 100, n = 50) table(probs) probs <- complete_rs_probabilities(N=100, prob = .3) table(probs) ```
