Inclusion Probabilities: Complete Random Sampling
complete_rs_probabilities(N, n = NULL, prob = NULL, check_inputs = TRUE)
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) |
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) |
check_inputs |
logical. Defaults to TRUE. |
A vector length N indicating the probability of being sampled.
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)
