[Gretl-users] New package: season_plot

Hi all, This package computes and depicts a time-series across sub-periods, also called a Buys-Ballot plot. For instance, if one has a quarterly time-series one can plot the dynamics of each quarter across years. Vice versa, you may also be interested in plotting the dynamics of each year's quarter. It's a kind of alternative to the existing package "|buys_ballot|" written by Ignacio Diaz-Emparanza and Riccardo (Jack) Lucchetti. However, "season_plot" allows you to plot _all_ frequency combinations. The main features are:  * Simple API.  * GUI access through the gretl menu.  * Source code is tested by means of unit-tests to minimize bugs. It requires that version 0.2 of the "multiplot" package is installed on your system. It's already available on the gretl package server: <hansl> pkg install season_plot include season_plot.gfn help season_plot </hansl> For a brief introduction see also here: https://github.com/atecon/seasonality_plot Best, Artur
