COMMUNICATION FROM THE COMMISSION Guidelines for national courts on how to estimate the share of overcharge which was passed on to the indirect purchaser · European Union
(92) There is a certain trade-off between the two error types in the following sense; for a given data sample size, further reducing the risk of type 1 errors (e.g., using a tighter, 99 percent confidence interval instead of the 95 percent interval) generally increases the risk of type 2 errors. In general, limiting both types of errors is only possible through increasing the sample size. Hence, in practice, it is important to assess whether the methods are applied on a sufficiently large dataset.
