X-13ARIMA-SEATS and iMetrica

This paper will give the latest developments in two ongoing software projects. One is a joint collaboration with the current developers of the SEATS seasonal adjustment program, X-13ARIMA-SEATS, officially released by the Census Bureau in 2012. This program combines the seasonal adjustment and modeling modules of the X-12-ARIMA program with the model–based seasonal adjustment module from SEATS. This program allows producers of seasonally adjusted series to generate X-11 and SEATS seasonal adjustments using the same interface, and compare these seasonal adjustments using a common set of diagnostics. The second is a software system named iMetrica, which is a unique GUI oriented software for both simulating and modeling from many different types of time series models. This software package focuses on speed, user interaction, visualization tools, and point-and-click simplicity for building models for time series data of all types and is written entirely in GNU C and Fortran with a rich interactive interface written in Java. One powerful feature that is unique to th
