Computes the approximate power of a Pearson or partial correlation test for a planned sample size. Set s = 0 for a Pearson correlation.

power.cor1(alpha, n, cor, h, s)

Arguments

alpha

alpha level for hypothesis test

n

planned sample size

cor

planning value of correlation

h

hypothesized value of correlation

s

number of control variables

Value

Returns the approximate power of the test

Examples

power.cor1(.05, 80, .3, 0, 0)
#>          Power
#> [1,] 0.7751932

# Should return:
#          Power
# [1,] 0.7751932
