WitrynaLoess Regression is the most common method used to smoothen a volatile time series. It is a non-parametric methods where least squares regression is performed in … Witryna6 sie 2015 · Fitting a linear model to logarithmized values (with lm) yields a different result than fitting the non-linear model (with nls) because different distances are minimized. For the logarithmized linear model, the logarithmized residuals are minimized, creating a bias away from bigger remaining residuals.
