June 5, 2014: We are excited to announce the release of the latest version of NumXL: 1.63 (SHAMROCK).
In addition to many fixes, the new version now thoroughly supports new ARMA-type models (e.g. ARIMA, Seasonal ARIMA, ARMAX, and SARIMA-X) and time series (Monte-Carlo) simulation.
With this update, NumXL will greatly streamline the process of creating robust ARMA/ARIMA models for everyday use with just a few easy clicks.
NumXL 1.63 will also add two new models (ARMAX and SARIMAX) to your factors analysis arsenal to help you get a handle on regression cases with correlated residuals. Furthermore, the new simulation functionality lets users conduct all sorts of ad-hoc scenarios and calculate sound statistics to further support their decision making processes.
Finally, the new version's improved functionality will help us make strides towards developing model detection and diagnosis functionality. This means we’ll soon offer various automatic model detection methodologies (e.g. Box-Jenkins), backtesting, and others.
Check out a video below that shows some of the features of NumXL 1.63.
