To minimize the error, we need to minimize the Linear Regression Cost Function. Lesser the cost function, better the learning, more accurate will be the predictions. More for You ...

In statistics, the sum of squares is used to calculate the variance and standard deviation of a dataset, which are in turn used in regression analysis. Analysts and investors can use these ...

Often, regression models that appear nonlinear upon first glance are actually linear. The curve estimation procedure can be used to identify the nature of the functional relationships at play in ...

In ANOVA we also compute the total and treatment sum of squares; the analogous quantities in linear regression are the total sum of squares, SST = (n–1)s 2 Y, and the regression sum of squares ...
