Linear regression .fit python
NettetRobust linear estimator fitting. ¶. Here a sine function is fit with a polynomial of order 3, for values close to zero. No measurement errors, only modelling errors (fitting a sine with a polynomial) The median absolute deviation to non corrupt new data is used to judge the quality of the prediction. TheilSen is good for small outliers, both ... NettetLinear Regression. Linear models with independently and identically distributed errors, and for errors with heteroscedasticity or autocorrelation. This module allows estimation by ordinary least squares (OLS), weighted least squares (WLS), generalized least squares (GLS), and feasible generalized least squares with autocorrelated AR (p) errors.
