WebEqual width discretization. Equal width binning is probably the most popular way of doing discretization. This means that after the binning, all bins have equal width, or represent an equal range of the original variable values, no matter how many cases are in each bin. With enough bins, you can preserve the original distribution quite well ... WebSupports binning into an equal number of bins, or a pre-specified array of bins. Parameters x array-like. The input array to be binned. Must be 1-dimensional. bins int, sequence of scalars, or IntervalIndex. The criteria to bin by. int : Defines the number of equal-width bins in the range of x.
