Conversion from Probability Difference to Cohen's h

Helper function to convert probability difference to Cohen's h (and vice versa).

Usage

probs.to.h(prob1, prob2 = 0.5, verbose = 1)

Arguments

prob1

Probability of success in the first group, or under the alternative hypothesis in the one-sample case).

prob2

Probability of success in the second group, or under the null hypothesis in the one-sample case).

verbose

1 by default (returns test, hypotheses, and results), if 2 a more detailed output is given (plus key parameters and definitions), if 0 no output is printed on the console.

h

Cohen's h effect size.

Value

h

Cohen's h effect size.

prob1

probability of success in the first group, or under the alternative hypothesis in the one-sample case).

prob2

probability of success in the second group, or under the null hypothesis in the one-sample case).

Examples

probs.to.h(prob1 = 0.56, prob2 = 0.50)
#>         h     prob1     prob2 
#> 0.1202899 0.5600000 0.5000000
