robustscale: Robust Estimation of Median (center) and MAD (scale)

Description

Smoothing spline estimate of median and mean absolute deviation (MAD).

Usage

robustscale(y, x, nslice=400, corcenter=TRUE, decrease=TRUE)

Arguments

y

response

x

predictor

nslice

number of slices (should be "large")

corcenter

correct for center

decrease

force MAD to decrease with x

Value

Data frame containing significant genes with the following information:

center

estimate of center median

scale

MAD estimate of scale

x

ordered x values for plotting

y

y sorted by x

Details

This divides data into roughly many nslice slices and computes median and mean absolute deviation (mad) for each slice. These are then smoothed using smooth.spline.
