loess group transformation
Philippe Rocca-Serra
A loess group transformation is a loess transformation where the input is partitioned into groups and for each group a loess fitting is performed, utilizing a subset of (or possibly all of) the data points in that group. Thus, a collection of loess curves y=f_i(x) is generated, one per group. Each (x, y) in the input is transformed into (x, y-f_i(x)), where f_i(x) is the curve corresponding to the group to which that data point belongs.
