In linear regression models, a metric predictor (e.g. age) is linked to the outcome by a linear function, with a slope and an intercept. A very common type of question is how an outcome changes by a set of discrete conditions, such as two different designs. Factorial model uses a ...

the natural log, we find that ln Yi = β1 + β2 Xi + ui, which becomes a linear regression model. (b) The following transformation, known as the logit transformation, makes this model a linear regression model: ln [(1- Yi)/Yi] = β1 + β2 Xi + ui ...

In this post we have discussed a model fitted with scikit-learn. The same steps presented could be used to fit different models such as LinearRegression (OLS), Lasso, LassoLars, LassoLarsIC, BayesianRidge or SGDRegressor, among others. More elaborate strategies can be used, such as using pip...
