Conversion from a correlation Difference to Cohen's q

Usage

cors.to.q(rho1, rho2, verbose = 1)

Arguments

rho1: first correlation.
rho2: second correlation.
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.

Value

q: Cohen's q effect size.
delta: correlation difference: rho1 - rho2.
rho1: first correlation.
rho2: second correlation.

Examples

cors.to.q(rho2 = 0.5712027, rho1 = 0.50)
#>          q      delta       rho1       rho2 
#> -0.1000000 -0.0712027  0.5000000  0.5712027 
cors.to.q(rho2 = 0.6907068, rho1 = 0.50)
#>          q      delta       rho1       rho2 
#> -0.3000000 -0.1907068  0.5000000  0.6907068 
cors.to.q(rho2 = 0.7815365, rho1 = 0.50)
#>          q      delta       rho1       rho2 
#> -0.5000001 -0.2815365  0.5000000  0.7815365
