13.1. Overall accuracy:The accuracy of Producer price index of industrial products for export is generally considered to be high. The accuracy of source data is monitored by assessing the methodological soundness of price and weight sources and the adherence to the methodological recommendations. Appropriate actions are taken to identify and eliminate potential sources of errors.
13.2. Sampling error:Sampling error can not be calculated because the survey was not conducted on the basis of a random sample.
13.3. Non-sampling error:The response rate is about 70%. Depending on their size or representatives, companies are contacted by phone in order to provide data on time. The price of the temporarily unavailable product is determined by contacting the company from which it is required to estimate/assess the missing price or to repeat the last declared price. In cases where an industrial enterprise ceases to produce a product of a certain quality for which the prices are collected, or if the product of that quality is 'non-marketable goods', then a new product of a certain quality that is best sold is defined and it is expected that it will be sold for a long time and in large quantities. Prices for the new selected product quality are given simultaneously for the current and previous month. Companies are required to explain any change in quality.
