Model setup For the modelling, use cross-validation by using vfold_cv() function with stratification on the price variable: vfold_cv(data, strata=variable) Provide an narration explaining why cross-validation and stratification is necessary in this case. Setup a recipe for the model by using at least 5 variables and at least 3 steps. Justify the selection of variables. Justify the selection of steps for the recipe Specify the model using one of the regression approaches. Explain your choice
