Catherine Hood Consulting


Catherine Hood Consulting specializes in statistical solutions for forecasting, data mining, and time series analysis, particularly in the area of seasonal adjustment.

With over 50 years combined experience, our focus is on statistically sound methods you can use in production. Our services include both consulting and seasonal adjustment training, especially on the X-13ARIMA-SEATS, X-12, and TRAMO/SEATS seasonal adjustment programs.

Whether you are forecasting, data mining, or analyzing a time series, you may need to estimate and remove a seasonal component. By removing the seasonal component, we can see patterns in the underlying data that were previously hidden. By estimating a seasonal component, we can include seasonal movements in the forecasts and more accurately forecast other phenomenon found in the processes related to your data.

Many government agencies collect and publish time series, and most of the sub-annual indicators are seasonally adjusted. Would you or your company benefit by gaining insight into the seasonally adjusted numbers published every month or quarter? Understanding seasonal adjustment can help us predict what various agencies will say about the economic indicators that they publish.

How does a year of pandemic affect the seasonal adjustments of published economic indicators? How can we forecast after a year marked by upheaval? We can help you answer these questions for your data of interest.
