Remove the value(s) most differing from the mean
Description:
This function can remove the outliers or replace by sample mean or median.
Usage:
[res] = rmoutlier(x,fill,median,opposite)
Arguments:
x: a dataset, most frequently a vector. If argument is a
matrix, each column is treated as independent dataset.
fill: If set to 1 (default 0), the median or mean is placed instead of
outlier. Otherwise, the outlier(s) is/are simply removed.
median: If set to 1 (default 0), median is used instead of mean in outlier
replacement.
opposite: if set to 1 (default 0), replaces opposite value (if largest value has
maximum difference from the mean, it replaces smallest and vice
versa)
Value:
A dataset of the same type as argument, with outlier(s) removed or
replaced by appropriate means or medians.
