corr.1samp: Power calculation for test of one correlation coefficient

In powertools: Power and Sample Size Tools

Power calculation for test of one correlation coefficient

Description

Calculates power and sample size for a test that the correlation coefficient in a single population is equal to (or less than or greater than) a specified value. Can solve for power, N or alpha.

Usage

corr.1samp(
  N = NULL,
  rho0 = 0,
  rhoA = NULL,
  alpha = 0.05,
  power = NULL,
  sides = 2,
  v = FALSE
)

Arguments

N	The sample size.
rho0	The correlation coefficient under the null hypothesis; defaults to 0.
rhoA	The correlation coefficient under the alternative hypothesis.
alpha	The significance level (type 1 error rate); defaults to 0.05.
power	The specified level of power.
sides	Either 1 or 2 (default) to specify a one- or two- sided hypothesis test.
v	Either TRUE for verbose output or FALSE (default) to output computed argument only.

Value

A list of the arguments (including the computed one).

Examples

corr.1samp(N = 100, rhoA = 0.2, sides = 1)
corr.1samp(N = 100, rho0 = 0.2, rhoA = 0.4, sides = 1)
