Sample size estimation for regression coefficient
$N = \Big(\frac{z_{(1-\alpha/2)}}{w}\Big)^2\Big(\frac{1-R^2}{1-R^2_{XX_j}}\Big) + p + 1$
where $R^2$ represents the population multiple correlation
coefficient predicting the criterion (dependent)
variable … $Y$ from the $p$ predictor variables and $R^2_{XX_j}$
represents the population multiple correlation coefficient
predicting the $j$th predictor from the remaining $p
− 1$ predictors. …
