SummaryOn methods of computation of index‐numbers of industrial production.When computing production‐index‐numbers at least three different weighting systems are available:1. man‐hours expended per unit; 2. value added per unit; 3. prices.According to the different aims for which production indices are to be used different weighting procedures should be applied, from which it follows that there is no unique index‐number, satisfying all conditions that may be enforced on them. If it is the aim to construct an index‐number of productivity of labour, it is shown that weighting with man‐hours is to be carried out. If however the aim is to have an index of the economic activity of industry, weighting with value added should be applied. In general, both man‐hours and value added are unknown for the separate products of one group of factories. Weighting with prices is therefore the only possible alternative.Finally the construction of an index of net industrial production, that is production minus the consumption of raw materials, is considered. It is shown that weighting of the net production by value added leads to weighting with prices of all production‐ and consumption‐items, quantities of the latter thereb

SummaryMethods for comparing, testing and estimating unknown probabilities.This expository paper deals with the 2 times 2‐table for comparing two probabilities. It gives the exact distribution under the hypothesis tested, the normal approximation and several methods for combining independent tests of this kind.Furthermore it deals with a test for the hypothesis H0: p = p0and gives exact methods and approximations for determining a confidence interval for an unknown probabilit
