How to use `lmplot` to plot linear regression without intercept?

WebRegression through the origin is a very useful version of regression, but it’s quite limited in its application. Rarely do we want to fit a line that is forced to go through the origin, or stated equivalently, rarely do we want a prediction algorithm for Y that is simply a scale change of X. Typically, we at least also want an intercept. Web99.62656. a. Predictors: Payout Ratio, Regression Beta, ln (Expcted Growth) b. For regression through the origin (the no-intercept model), R Square measures the proportion of the variability in the dependent variable about the origin explained by regression.
