## 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` |

### 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`

.

### 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` |
