I am looking for an alternative tool (proprietary or FOSS) that matches the functionality of Temporal Analyst for ArcGIS by DHI Software. The best I could get was the QGIS plugin Time Manager whose functionality I perceive is more for visualisation than analytical (similar to esri's Time Slider.)
[Data Analysis - the Temporal Analyst for ArcGIS offers a suite of tools for data analysis and processing, incl. basic statistics and arithmetics, time step resampling, gapfiling, distribution and CDF plots, duration curves, double mass and double scatter.]
I am not a statistician nor hardcore developer so the more the "point and click" I can get the better. Thank you for all the pointers.
