Every predictor added to a model increases R-squared and never decreases it. WebbIn simple linear regression, the model contains a random dependent (or response or outcome or end point) variable Y, that is hypothesized to be associated with an independent (or predictor or explanatory) variable X. The simple linear regression model speciﬁes that the mean, or expected value of Y is a linear function of the level of X. bow badgers fc

WebbThe answer is that we cannot decide on the global significance of the linear regression model based on the p-values of the β coefficients. This is because each coefficient’s p-value comes from a separate statistical test that has a 5% chance of being a false positive result (assuming a significance level of 0.05).
