Dataset:TOPSI: Manufacturing export turnover
10 August 2017
In the next release of Turnover in Production and Services Industries (TOPSI) July 2017 to be published on 8 September 2017, the monthly business survey data feeding into this release will contain new imputation methodology to survey non-response back to January 2016. For respondents that do not return data in a given month, the turnover and export values are imputed using a ratio imputation method called the mean of ratios. The new method, referred to as the ratio of means is more stable and reduces imputation bias. We will publish an article on the impact with the next release of TOPSI.
In addition to the usual TOPSI release tables this month we have published export proportions which are calculated as a proportion of total sales. This table used to accompany the IoP release but will now be published alongside TOPSI every month.
