"WebApr 14, 2024 · Equal width (or distance) binning : The simplest binning approach is to partition the range of the variable into k equal-width intervals. The interval width is simply the range [A, B] of the variable divided by k, w = (B-A) / k. Thus, i th interval range will be [A + (i-1)w, A + iw] where i = 1, 2, 3…..k Skewed data cannot be handled well by this method. " - Binning discretization
