NettetIn linear regression, intercept and coefficients are estimated by minimizing the sum of squared residuals. That particular model resulted a negative intercept alongside the coefficient estimates. Unlike logistic regression, the output of linear regression is not bounded so you can have negative values. therealtiddlydump • 2 hr. ago.
