Built the linear regression model using “GLM” package. It’s very similar to the “GLM” package in R. Let’s start with 1 variable. To train a linear regression model, use the lm() function that accepts a formula object as the first argument. Use the @formula to create the required...
Thank you so much for this site. It is very helpful. I have to make a project for bachelor’s degree but I don’t know how to find some data so I can make the regression analysis. I want you to tell me what variable to take, to make the regression analysis?I have the theme of...
In this recipe, we'll look at how well our regression fits the underlying data. We fit a regression in the last recipe, but didn't pay much attention to how well we actually did it. The first question after we fit the model was clearly "How well does the model fit?" In this recip...

using stepwise regression.stepwiseglmstarts from one model, such as a constant, and adds or subtracts terms one at a time, choosing an optimal term each time in a greedy fashion, until it cannot improve further. Use stepwise fitting to find a good model, one that has only relevant terms....
In general, a linear regression model can be a model of the form yi=β0+K∑k=1βkfk(Xi1,Xi2,⋯,Xip)+εi, i=1,⋯,n, wheref(.) is a scalar-valued function of the independent variables,Xijs. The functions,f(X), might be in any form including nonlinear functions or polyno...
