LDA is mainly used in classification problems where you have a categorical output variable. It allows both binary classification and multi-class classification. The standard LDA model makes use of the Gaussian Distribution of the input variables. You should check the univariate distributions of each ...

cat_var may be numeric or string; it is shown on the categorical x axis. graph hbar draws horizontal bar charts. In a horizontal bar chart, the numerical axis is still called the y axis, and the categorical axis is still called the x axis, but y is presented horizontally, and x ...
Different from classification where predicted output values are categorical, regression models predict numerical output values based on independent predictors. In regression, the objective is to help establish the relationship among those independent predictor variables by estimating how one variable impacts th...
