The earlier versions of our method MASH (Multiple Analysis of Series for Homogenization;
Szentimrey) were developed for homogenization of the daily and monthly data series
in the mean, i.e., the first order moment. The software MASH was developed as an interactive
automatic, artificial intelligence (AI) system that simulates the human intelligence
and mimics the human analysis on the basis of advanced mathematics. This year we finished
the new version MASHv4.01 that is able to homogenize also the standard deviation,
i.e., the second order moment. The problem of standard deviation is related to the
monthly and daily data series homogenization.
