n_effective_R2: Effective sample size

Description

Estimate an effective sample size for a statistic given the observed statistic and the estimated sampling error variance (cf. Revelle et al., 2017).

Usage

n_effective_R2(R2, var_R2, p)

Value

An effective sample size.

Arguments

R2

Observed R^2^ value

var_R2

Estimated sampling error variance for R^2^

p

Number of predictors in the regression model

Details

n_effective_R2 estimates the effective sample size for the R^2^ value from an OLS regression model, using the sampling error variance formula from Cohen et al. (2003).
