Scaled mad

WebSCALE_MAD: Scaling MAD datasets. SCALE_MAD is a routine to read in MAD data from a Scalepack output file or from another formatted file and to scale it and put it all in a file suitable for ANALYZE_MAD and SOLVE. It is ordinarily called as the first step in a completely automated structure determination and is followed by ANALYZE_MAD and SOLVE. WebBy default, an outlier is a value that is more than three scaled median absolute deviations (MAD) from the median. example TF = isoutlier (A,method) specifies a method for detecting outliers. For example, isoutlier (A,"mean") returns true for all elements more than three standard deviations from the mean.
