WebAnalysis of Variance (ANOVA) is a parametric statistical technique used to compare data sets. This technique was invented by R.A. Fisher, hence it is also referred to as Fisher’s ANOVA. It is similar to techniques such as t-test and z-test, to compare means and also the relative variance between them. Similarly, A t-test can be used to ... Web12 feb. 2024 · 1 You can use the variance of the regression. σ ^ 2. Since u ^ ′ u ^ = S Q R. So we can say that S Q R = σ ^ 2 ∗ ( T − k − 1). In your case k = 3 because you have 3 parameters; so you need to remove the − 1 from the denominator because you don't have the intercept term in your model.
