DataTrim cleans the data through a pseudo winsorization algorithm. First, the mean and SD are calculated. Then, any values above 2SD are trimmed.The mean is recalculated and any values less then 2 SD are trimmed.This process of cutting 2 SD above the mean and then 2 SD below the mean is repeated until no further cuts are possible.
chipdata is a vector of chipdata from microarray chips.
Returns a vector of trimmed chipdata representing background based on pseudo winsorization algorithm.
