WebWe can create groups by dividing length of a in equal number of bins and use ave to calculate rounded mean in each group. no_of_bins <- 4 round(ave(a, rep(1:length(a), each = no_of_bins, length.out = length(a)))) #[1] 9 9 9 9 23 23 23 23 29 29 29 29 PS - ave has default function as mean so it has not been explicitly applied. 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 ... flock license plateWebDec 28, 2024 · Binning would be wise to apply if your continuous variable is noisy, meaning the values for your variable were not recorded very accurately.
