3.1. Data description

Statistics on eggs for hatching and farmyard poultry chicks are collected under (market) Regulation (EC) No 617/2008. They are the earliest available information to foresee production of poultry meat and eggs, as the numbers of chicks of various utilities placed in the farms of each Member State, i.e. the number of chicks placed by the hatcheries of this Member State increased by the net import of chicks.

Imputation: Since this universe is rather small in PT, response rate is usually 100%, so imputation is rarely used.

                     Description of the methods: 

                         Imputation by simple copy or average 

                           Imputation by simple copy consists of entering on the missing questionnaires the data from the questionnaire of the previous month or the same month of the previous year, for the same respondent. Sometimes the average of the data from the previous months' questionnaires is chosen for the missing respondent.

                         Imputation with trend coefficient

                           The imputation with trend coefficient is performed in two steps. First the coefficient is calculated that corresponds to the trend between the response data obtained for the month in question and the data from the homologous month of the year Y-1 corresponding to the same set of informants. The second stage concerns the application of this coefficient to the data from the homologous questionnaire of the same respondent.

Other referred procedures in data compilation are not applicable.
