Power And Sample Size Calculations For Studies Involving Linear Regression.

Calculating sample size with scientific justification is critical for. But the problem with the calculation is that it is based on assumptions on these inputs, and not necessarily the ‘best’ or ‘correct’ values. For a given power, it also allows to calculate the sample size that is necessary to reach that power.
