We can construct an efficient and reliable solution allowing for production of SA series, by using state-of-the art methods and techniques and maintaining the closest control of your data quality.

Seasonality of the series is a significant factor in the explanation of fluctuations of the series, therefore taking it into account must be made in all interpretations or analysis.

By identifying and removing seasonality from original series we can give gives an insight into short-term trends because the seasonal effects can disguise important features of economic series such as:

  • Direction
  • Turning points
  • Consistency between other economic indicators
