摘要:
SummaryAsymptotically efficient rank invariant test procedures for detecting differences between two groups of independent observations are derived. These are generalized to test between two groups of independent censored observations, to test between many groups of observations, and to test between groups after allowance for the effects of .concomitant variables.One of these test procedures—the logrank—is particularly appropriate for comparing life tables, and can therefore be used in the analysis of clinical trials, industrial life‐testing experiments and laboratory studies of animal carcinogenesis. It has greater local power than any other rank‐invariant test procedure for detecting Lehmann‐type differences between groups of independent observations subject to some right‐censoring. The logrank test, although a rank test, can be presented in a format which exhibits the physical significance as well as the statistical significance of any important differences between groups of events.

摘要:
SummaryCapital usage in six groups of the U.K. manufacturing industries have been calculated using electricity consumption data for the years 1955‐68 inclusive. These series are compared with capital usage figures based on:1. The Confederation of British Industry's survey of “capacity” usage,2. Output/capital ratio variations, and3. Complementary labour inputs.The comparisons lend some weight to the criticisms often levelled at these three measures of capital usage.The advantages claimed for the electricity consumption method of measuring capital usage arise from the unique properties of electricity as an homogeneous, non‐storable input of invariate quality for which maximum consumption can be estimated.There are reasons for not regarding the electricity consumption series as an absolute measure of capital usage but they may nevertheless be useful for inter‐regional and international comparisons of similar industry groups. Comparison with the U.S. data suggests a 30 per cent lower usage in the U.K. and a slower rate of increase in usage.

摘要:
SummaryCasino pontoon is a convenient descriptive name for a variant of the American game of blackjack. Often under the name of blackjack it was played in clubs in the Midlands during the decade 1960‐70, before the implementation of the Gaming Act of 1968. It was the subject of several successful prosecutions for unlawful gaming under the Acts of 1960 and 1963. The results of an investigation into its properties, which formed the basis of these prosecutions, are presented in this paper. This investigation yielded,inter alia,an optimum strategy for the player. Although the game is not lawful under present gaming regulations some of the results presented here are qualitatively relevant to the domestic game of pontoon.

摘要:
SummaryA two‐stage dynamic model has been developed to represent the process of labour turnover. The model provides a good fit to a wide range of published turnover data. Labour turnover is defined in terms of primary and secondary termination processes separated by an induction period. The rates of the two termination processes vary markedly between firms; firms with low initial labour turnover rates do not necessarily have low secondary labour turnover rates and vice versa. The rates at which recruits adapt to the ways of different firms are markedly similar. The parameters controlling the turnover process seem to have a realistic significance in terms of quantifying some of the factors involved in the interaction of personnel and organizations. If the model is valid, then its use in the analysis of labour turnover data would make it relatively easy for a particular firm to pinpoint (and control) those factors which result in its particular type and level of labour turnover. Examples are given of the use of the model for evaluating the likely consequences of parameter modification (policy changes).

摘要:
SummaryThis paper is a study of the nature of the frequency distribution of the duration of strikes in the United Kingdom as recorded by the Department of Employment. The settlement of a strike is regarded as a probabilistic process and the duration of a strike is treated as an observation on a random variable. A model for this random duration is created by supposing that at each point of time after the commencement of a strike there exists an index of the difference between the parties to the dispute. This index is itself regarded as a one‐dimensional stochastic process in continuous time and space and determines the duration of the strike by the first point of time at which the difference index passes through an absorbing barrier representing “agreement”. The duration of a strike then becomes the First Passage time of a stochastic process to a single absorbing barrier. As a first approximation the index process is assumed to be simple Brownian motion with drift and in consequence the duration of a strike has the Inverse Gaussian for its probability distribution. The fit of this distribution to the observations is shown to be, with few exceptions, very close.
