%description
Implementation of the SSR-Algorithm. The Sign-Simplicity-Regression model
is a nonparametric statistical model which is based on residual signs and
simplicity assumptions on the regression function. Goal is to calculate
the most parsimonious regression function satisfying the statistical
adequacy requirements. Theory and functions are specified in Metzner
(2020, ISBN: 979-8-68239-420-3, "Trendbasierte Prognostik") and Metzner
(2021, ISBN: 979-8-59347-027-0, "Adäquates Maschinelles Lernen").
