Partial F Test Formula. The formula for partial f statistic is defined as here sse is the sum of the squares of error and mse is the mean of the sum of the squares of error. Definitions for regression with intercept n is the number of observations p is the number of regression parameters.
The test statistic can be obtained by computing the ratio of the two variances s a 2 and s b 2. Anova fit 1 fit 2 analysis of variance table model 1. Application of partial f statistic.

The partial f statistic can be written in several ways. Application of partial f statistic. What we are testing therefore is whether the difference is so large that the removal of the variables will be detrimental to the model. Inf 0 135 0 613 area 0 2435 x2 0 0657 x3.
