a. When X_1i is equal to log(X_1i) and both X_1i and X_2i are included as regressors. What is the value of SS (sum of squared deviations)for the following sample? Sample: 1, 3, 2, 2 A)0.50 B)2 C)4 D)18 Prove tha...
Thesum of squares total(SST)or thetotal sum of squares (TSS)is the sum of squared differences between the observeddependent variablesand the overallmean. Think of it as the dispersion of the observed variables around themean—similar to thevariancein descriptive statistics. But SST measures the ...
