Sample size for an interval test of a Pearson or partial correlation
Source:R/statpsych2.R
size.interval.cor.Rd
Computes the sample size required to perform an interval test for a population Pearson or a partial correlation with desired power where the interval midpoint is equal to zero. This function can be used to plan a study where the goal is to show that the population correlation is small. Set s = 0 for a Pearson correlation. The correlation planning value must be a value within the hypothesized interval.
