SA refers to ''seasonal adjustment,'' which is a statistical method used to remove effects of seasonal patterns in a dataset. SAAR stands for ''seasonally adjusted annual rate,'' which means the data is seasonally adjusted and annualized. We mark a dataset with ''(SA, YoY)'' to indicate that the data has been seasonally adjusted and is compared with the same period last year (also known ''year-on-year''). Indicators not accompanied with any of these abbreviations are generally not seasonally adjusted (NSA).
MoM and QoQ mean the data is compared with the previous month or quarter.
Lastly, there is also CA, which stands for ''calendar adjustment,'' a statistical method for removing the calendar effects from the data, taking into account variation in the number of holidays in different months.
What do the different abbreviations like SA, NSA, SAAR, YoY, MoM, QoQ, and CA mean?
