| PSC107E - Turnover volume indices in market services rendered to the population, working day adjusted series - base year 2005 |
| Definition |
The net turnover is calculated by summing up the invoiced returns from the sale of goods and commodities, the performance of works and services. Turnover does not include VAT, excise duties, subsidies received from public authorities or EU institutions and income from sale or transfer of fixed assets. Market services rendered to the population include the following activities: hotels and restaurants, travel agency, tour operator reservation service and related activities, gambling and other recreation activities, hairdressing and other beautifying activities, washing and (dry) cleaning of textile and fur products, funeral activities, body building and other services for natural persons (class of CANE Rev.2: 9603, 9604, 9609,9313). |

Statistical survey on turnover in industry details |
| Methodology |
The adjusted series with working days number was obtained by eliminating from unadjusted series these effects by means of correction coefficients, set up according to the regression model (additive or multiplicative).
Regression models used for each series are set up at the begining of each year involving the recalculation of adjusted series calculated in the previous year (recalculation due to the adopted models change, number of regresors used and number of available observations).
Aggregate levels were adjusted by 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 origin components).
Unobserved components: trend-cycle,seasonality and irregular components are estimated by means of the SEATS program based on ARIMA models.
The adjusted series of working days effect and seasonality is obtained by eliminating seasonal component from adjusted series of working days effect.
Turnover value indices in market services rendered to the population are of Laspeyres type and are calculated as nondeflated weighted indices. The weights used at aggregation are calculated based on turnover according to the results of Structural Business Survey (2005).
