But only Wealth has a p-value < 0.05. Should the model be used as is? WebbThe test statistic of the F-test has the same PDF as that of the F-distribution. In other words, the F-statistic follows the F-distribution. STEP 3: Calculating the value of the F-statistic. If you use statsmodels’s OLS estimator, this step is a one-line operation. All you need to do is print OLSResults.summary() and you will get:

Webb'P> t '. Typically, a t-statistic above 2 or below -2 is considered significant at the 95% level. We use 2 as a rule of thumb because in the t-distribution we need to know how many degrees of freedom we have (d.f. = number of observations - number of variables) before we can decide whether the value of the t-statistic is significant at the 95%
