• A DUAL TO RATIO ESTIMATOR IN SAMPLE-SURVEYS AI翻译
  作者：SRIVENKATARAMANA, T
  摘要：This paper proposes a new product-type estimator which is complementary to the commonly used ratio estimator. Exact formulae for the bias and mean squared error can be derived which is not the case for the ratio estimator. The correction of the new estimator for bias is examined. A brief empirical study is also included.
• CONSEQUENCES OF THE USE OF CONDITIONAL INFERENCE IN THE ANALYSIS OF A CORRELATED CONTINGENCY TABLE AI翻译
  作者：FRISEN, M
  摘要：Analysis of a correlated contengency table is needed in a comparison of 2 forms of medical treatment [drugs, surgery]. Some consequences of the common practice of adopting conditional inference are derived and discussed.
• ROBUST ESTIMATORS FOR QUANTAL BIOASSAY AI翻译
  作者：MILLER, RG; HALPERN, JW
  摘要：Extensions of robust estimators for the location of a symmetric distribution are given for the quantal bioassay problem. Asymptotic properties of the estimators are derived. A comparison in terms of asymptotic efficiencies under different tolerance distributions is made between the Spearman-Kaerber estimator and the trimmed mean and Tukey biweight estimators.

• ASYMPTOTIC EXPANSIONS FOR THE DISTRIBUTIONS OF THE SAMPLE ROOTS UNDER NON-NORMALITY AI翻译
  作者：FUJIKOSHI, Y
  摘要：The distribution of latent roots of the sample covariance matrix is studied when the parent population is nonnormal. Asymptotic expansions of the marginal and joint distributions of the sample roots and the distribution of a function of the sample roots are given by finding the Edgeworth expansions.

• OPTIMAL CONFIDENCE-INTERVAL FOR THE LARGEST MEAN IN REPEATED MEASUREMENTS DESIGN AI翻译
  作者：CHEN, HJ; TSAI, PJ
  摘要：A single-stage sampling procedure is proposed for obtaining an optimal confidence interval on the largest or smallest mean of k variates in a repeated measurements design. The variates are assumed to obey a multivariate normal distribution with common and known correlation coefficient with the common variance being known or unknown. Percentage points to apply this procedure are also provided.
• SAMPLING SCHEMES PROVIDING UNBIASED REGRESSION-ESTIMATORS AI翻译
  作者：SINGH, P; SRIVASTAVA, AK
  摘要：A sampling scheme is proposed for which the usual regression estimator is unbiased. Another sampling scheme with an unbiased regression-type estimator is also considered. On comparing the efficiencies of these sampling strategies with some existing strategies, the performance of the 1st of the new schemes is highly satisfactory.
• ON THE SPREAD OF A DISEASE WITH GAMMA-DISTRIBUTED LATENT AND INFECTIOUS PERIODS AI翻译
  作者：ANDERSON, D; WATSON, R
  作者单位：University of Melbourne
  摘要：A model is investigated with assumptions as for the so-called general epidemic model, except that the latent and infectious periods are independently gamma distributed. For this model, results were obtained concerning the progress of the epidemic. These results allow assessment of the effects of the latent period and the infectious period on the behavior of the epidemic model. Many of the results can be generalized.
