y
on predictor variable x
, separately within values of a third variable z
. It is used by maNormLoess
for intensity dependent location normalization.
maLoess(x, y, z, w=NULL, subset=TRUE, span=0.4, ...)
span
which controls the degree of smoothing in the loess
function.y
is regressed on x
, separately within values of z
using the loess
function.
