WebBinning numerical variables. Binning is the process of dividing continuous numerical variables into discrete bins. This can help to reduce the number of unique values in the feature, which can be beneficial for encoding categorical data. Binning can also help to capture non-linear relationships between the features and the target variable. WebMar 5, 2024 · You need to transfer the categorical variable to numerical to feed to the model and then comes the real question, why we convert it the way we do. We convert an n level of the categorical variable to n-1 dummy variables. There are two main reasons for it: Do avoid the collinearity into the created dummy variables
Web3. A reluctant argument for it, on occasion: It can simplify clinical interpretation and the presentation of results - eg. blood pressure is often a quadratic predictor and a clinician can support the use of cutoffs for low, normal and high BP and may be interested in comparing these broad groups. – user20650.
