TL;DR: In this paper, the authors study the differeut properties of the F-test which point out its merits and demerits from the point of view of errors of the first and second kind.

Abstract: The technique of analysis of variance is a powerful statistical tool in tracing the sources of variation of an observed random variable to different assignable causes. But the ease of calculations and the readily available F-test have made possible its somewhat uncritical applications in some cases. As a test of significance it should, however, derive its justification from the measure of control · it might effect over errors of different types involved ; and this has to be realised all the more because this test very often precedes any detailed analysis of the results. As for example, in judging the differences between the yields of a number of varieties of any particular crop, say rice, first of all we apply a comprehensive F-test embracing all the varieties simultaneously, and only when this comes out to be significant we proceed to analyse the individual differencesi. Hence there is the need of investigating whether the commonly applied F-test takes adequate account of the individual differences and whether any alternative procedure might appear to be better in particular situations. In this article we study the differeut properties of the F-test which point out its merits and demerits f . cm the point of view of errors of the first and second kind and v. hich also wggest a useful modification of the analysis of variance procedure for certain types of problems. For this purpose we will consider throughout the following simpler formulation (i.e. canonical form) of the problem, and at the

TL;DR: A balanced incomplete block design with parameters, v, b, r, k,.\\ is said to be resolvable if the blocks of a design are separable into r sets of n blocks each as mentioned in this paper.

Abstract: 1. A balanced incomplete block design with parameters, v, b, r, k, .\\ is said to be resolvable if the blocks of a design are separable into r sets of n blocks each (implying b=nr) in such a way that each variety occurs only once among the n blocks of a set forming a complete replication (obviously v=nk). Bose ( 1942 ) has proved a number of relations obtaining among the parameters of a resolvable design. The important ones are as follows :-

TL;DR: In this paper, a very flexible family which contains the gamma distrihution as a particular case is introduced, and the gamma distribution is used to model hydrological processes.

Abstract: Gamma distributions are some of the most popular models for hydrological processes. In this paper, a very flexible family which contains the gamma distrihution as a particular case is introduced. T...
