WebRunning a logistic regression model. In order to fit a logistic regression model in tidymodels, we need to do 4 things: Specify which model we are going to use: in this case, a logistic regression using glm. Describe how we want to prepare the data before feeding it to the model: here we will tell R what the recipe is (in this specific example ... WebApr 1, 2024 · Using this output, we can write the equation for the fitted regression model: y = 70.48 + 5.79x1 – 1.16x2. We can also see that the R2 value of the model is 76.67. This means that 76.67% of the variation in the response variable can be explained by the two predictor variables in the model. Although this output is useful, we still don’t know ...
