Data sources |
Statistical survey on industrial products and services - monthly, since 2005 details |
Methodology |
To adjust the gross series, the JDemetra+ software package (TRAMO / SEATS) was used, estimating the effect of working days number, different from one month to another and the calendar effect (leap year and other national holidays) as well as for the identification and correction of outliers. The working days adjusted series was obtained by eliminating these effects from the unadjusted series supported by some correction coefficients. Aggregated levels (section, total industry, main industrial groupings) were adjusted by means of direct method supposing direct adjustment of aggregated series. Using the direct method could lead to some inconsistencies in data series (respectively, aggregates should not be always ranging between the values of their original components).
