Abstract: A method of estimating a parameter relating to an upgrade of a wind turbine software includes toggling the wind turbine alternatingly between two modes, where the upgrade is implemented in one but not the other. Data is collected during toggling and divided into pairs of data parts, one from each mode. The data from the two modes is ordered separately and a quantile-to-quantile comparison is made.
