Web1.1 Dealing with Collinearity by Deleting Variables Since not all of the pvariables are actually contributing information, a natural way of dealing with collinearity is to drop some variables from the model. If you want to do this, you should think very carefully about which variable to delete. As a concrete example: if we try to include all of a To remove multicollinearities, we can do two things. We can create new features or remove them from our data. Removing features is not recommended at first. The reason is that there’s a possibility of information loss because we remove that feature. Therefore, we will generate new features first. From the … Meer weergeven For the demonstration, we will use a dataset called Rain in Australia. It describes the weather characteristics on different dates and locations. This dataset is also a … Meer weergeven After we load the data, the next step is to preprocess the data. In this case, we will not use the categorical columns and remove rows … Meer weergeven In this case, we will use the Support Vector Machine (SVM) algorithm for modeling our data. In short, SVM is a model where it will create a hyperplane that can separate data with different labels at a maximum … Meer weergeven After we have the clean data, let’s calculate the Variance Inflation Factor (VIF) value. What is VIF? VIF is a number that determines whether a variable has multicollinearity or not. That number also represents … Meer weergeven
