| cumsumbinning {MESS} | R Documentation |
Fast binning of cumulative vector sum with new groups when the sum passes a threshold or the group size becomes too large
cumsumbinning(x, cutoff, maxgroupsize = NULL)
x |
A matrix of regressor variables. Must have the same number of rows as the length of y. |
cutoff |
The value of the threshold that the cumulative group sum must not cross. |
maxgroupsize |
An integer that defines the maximum number of elements in each group. NULL (the default) corresponds to no group size. |
Missing values (NA, Inf, NaN) are completely disregarded and pairwise complete cases are used f
An integer vector giving the group indices
