loc_median_fit {glmGamPoi} | R Documentation |
This function fits y based on x through a (weighted) median using
the npoints/2
neighborhood.
loc_median_fit( x, y, fraction = 0.1, npoints = max(1, round(length(x) * fraction)), weighted = TRUE, ignore_zeros = FALSE )
x, y |
the x and y coordinates of the points. |
fraction, npoints |
the fraction / number of the points that are
considered for each fit. |
weighted |
a boolean that indicates if a weighted median is calculated. |
ignore_zeros |
should the zeros be excluded from the fit |
This function is low-level and should usually not be called by the user.
