Although there are small discrepancies between the regression factor scores and the Bartlett factor scores, overall they appear to agree well for this data set. Table III. Regression and Bartlett Factor Scores Calculated from the Result of a Maximum-Likelihood Factor Analysis after Promax Rotation ...
Describe the issue linked to the documentation The documentation page for the fit method of the LinearRegression class mentions that the sample_weight parameter must be of type array_like or None (docs). However this is not entirely true...

, one can allow for infinite values \(\vert \hat{\gamma }\vert _2\rightarrow \infty \) . in this case, given linear separation, the set of solutions to eq. 1 are all estimators, which separate the data. alternatively, one can modify the objective ( 1 ). for example, agresti ...
