The column means are 2.3 for column 1, 1.85 for column 2 and 2.15 for column 3.
The general regression model with n observations and k explanators, the first of which is a constant unit vector whose coefficient is the regression intercept, is where y is an n × 1 vector of dependent variable observations, each column of the n × k matrix X is a vector of observations on one of the k explanators, is a k × 1 vector of true coefficients, and e is an n × 1 vector of the true underlying errors. The ordinary least squares estimator for is WebThe Total Sum of Squares is proportional to the variance in your data. It is the variance that the Mean Model wasn’t able to explain. Because TSS/N is the actual variance in y, the TSS is proportional to the total variance in your data.. Being the sum of squares, the TSS for any data set is always non-negative.
