In truelies: Bayesian Methods to Estimate the Proportion of Liars in Coin Flip Experiments

Description

Using simulations, estimate power to detect differences in lying using compare_dists(), given values for λ, the probability of lying, in each sample.

Usage

power_calc_difference(N1, N2 = N1, P, lambda1, lambda2, alpha = 0.05,
  alternative = c("two.sided", "greater", "less"),
  prior = stats::dunif, nsims = 200)

Arguments

N1	N of sample 1
N2	N of sample 2
P	Probability of bad outcome
lambda1	Probability of lying in sample 1
lambda2	Probability of lying in sample 2
alpha	Significance level
alternative	"two.sided", "greater" (sample 1 is greater), or "less". Can be abbreviated
prior	Prior over lambda. A function which takes a vector of values between 0 and 1, and returns the probability density. The default is the uniform distribution.
nsims	Number of simulations to run

Value

Estimated power, a scalar between 0 and 1.

Examples

power_calc_difference(N1 = 100, P = 0.5, lambda = 0, lambda2 = 0.25)
