spkAccSD: Accuracy Standard Deviation
In spkTools: Methods for Spike-in Arrays

Estimates the standard deviation for spike-ins at the lowest possible fold change in each bin.

1	spkAccSD(object, spkSlopeOut, tol=3)

`object`	a SpikeInExpressionSet object
`spkSlopeOut`	the output from the spkSlope function
`tol`	number of digits after decimal point

returns the median absolute deviation (MAD) for each bin.
