Web31 dec. 2024 · We find the following: n: 10. R2new: 0.600395. Thus, our Chi-Square test statistic for the Breusch-Pagan test is n*R2new = 10*.600395 = 6.00395. The degrees of freedom is p = 3 predictor variables. According to the Chi-Square to P-Value Calculator, the p-value that corresponds to X2 = 6.00395 with 3 degrees of freedom is 0.111418. WebTo determine whether to reject the null hypothesis using the t-value, compare the t-value to the critical value. The critical value is t α/2, n–p-1, where α is the significance level, n is the number of observations in your sample, and p is the number of predictors.

Having a high value for 1 -b (near 1.0) means it is a good test, and having a low value (near 0.0) means it is a bad test. Hence, 1 -b is a measure of how good a test is, and it is known as the “power of the test.” WebThe first thing to recognize is that failing to reject the null hypothesis might not be an error.
