strategy, it’s the most popular for this kind of task, since the outputs of the regression (coefficients) are unbiased estimators of the real values of alpha and beta. Indeed, according to the Gauss-Markov Theorem, under some assumptions of the linear regression model (linearity in parameters...
Whether a statistical method is appropriate for your data is partly determined by the measurement level of your variables. Regression analysis requires the following variable types: Variable types required for regression analysis : Independent variables: One or more quantitative of interval or ratio ...
