great tool for a fraction of the price that you pay for 3rd party software providers

Very easy to work with, especially being a simple add-on in Excel. I can easily seasonally adjust all data, forecast, and more. The customer support is one of the best I have ever experienced, which has been a huge benefit. I have reached out with questions late on Sunday evenings and have gotten them answered immediately. Now that is customer support!

I was initially looking for an Excel-based solution to perform seasonal adjustments on my economic time series as I found X-13 Arima-Seats to be very cumbersome and NumXL exceeded my expectations with its user-friendly add-in interface. I followed their online tutorials which usually comes with Excel spreadsheets to showcase how it’s done and everything worked very intuitively. The software comes with other tools that might come in handy (Descriptive Stats, Statistical Tests, Modeling, etc.) depending on the financial research topic / assignment you are working on. In my case, I also use multiple regressions often and I was happy to find out the software comes with a more advanced version of this Excel tool. It also allowed me while crafting my model to take decisions about variables to include or exclude based on one-click statistical tests such as the Multi-Collinearity test.
