Catherine Hood Consulting specializes in statistical solutions for forecasting, data mining, and time series analysis, particularly in the area of seasonal adjustment. Our focus is on statistically sound methods you can use in production, not simply a research report. Our services include both consulting and seasonal adjustment training, especially on the X-12/X-13-ARIMA 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.
We can help you set up options for the various types of seasonal adjustment software available, particularly X-12/X-13-ARIMA and TRAMO/SEATS.
We offer both project-by-project consulting and a subscription service. For more information, please see our Services page.
Forecasting can be difficult, especially if you are dealing with information that contains seasonal patterns, product life-cycles, shifts due to outside forces, or hundreds of other possible events. Though it's impossible to predict the future perfectly, of course, using monthly or quarterly seasonal models that take seasonal patterns, cycles, shifts and outliers into account can greatly improve your forecasts.
Seasonal patterns can often mask patterns that are useful. By removing the seasonal patterns, we can see features and patterns in the data that would otherwise be hidden.
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.
Catherine teaches a wide range of courses on the subject. More information on courses and other services can be found on the Courses page.
Short of taking a course, how can you learn more about seasonal adjustment? Check out our Frequently Asked Questions (FAQ) and papers pages. We also have some links to free seasonal adjustment software.
We are driven by a focus on our customers, working to deliver quality, tested products that are beyond expectations, anticipating needs and responding to requests when needed. Our experience is not only with finding proper methods, but also in putting the methods into production. We believe that solutions to your specific problems mean more than just a research report, but solutions that can be used in practice and in production. We offer a variety of services to help you meet your goals. For more information, please see our Services page and our Courses page.
