Make sure to also check out our Lunar age calculator and find out your age ...Recall that OLS minimizes the sum of the squared residuals for a model. Unusual cases – which by definition will have large outliers – have the potential to substantially influence our estimates of BB because their already large residuals are squared. A large outlier can thus result in OLS estimates that change the model intercept and slope.

We typically use a t -statistic to quantify whether an inferred coefficient was likely to have happened by chance. I discuss hypothesis testing and t -statistics for OLS.

OLS regression is based on several assumptions which, if violated, may render the results unreliable. The most important assumptions are independence, homoscedasticity, and normality of residuals. Independence of residuals assumes that residual of one observation is independent from residual of another observation.
