• 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.
• MAXIMUM-LIKELIHOOD ESTIMATION OF A DISTRIBUTION FUNCTION WITH INCREASING FAILURE RATE BASED ON CENSORED OBSERVATIONS AI翻译
  作者：PADGETT, WJ; WEI, LJ
  摘要：The maximum likelihood estimator of a distribution function with increasing failure rate is derived based on a set of observations subject to arbitrary right censorship. This estimator is defined everywhere on the positive real line while the Kaplan-Meier estimator may not be. The small sample properties of this estimator are indicated by results of a Monte Carol study for the Weibull distribution. [Applicability to life-testing and survival studies is discussed].
• THE INFLUENCE OF EXPERIMENTAL-DESIGN ON ROBUSTNESS TO NON-NORMALITY OF THE F-TEST IN REGRESSION-ANALYSIS AI翻译
  作者：VUCHKOV, IN; SOLAKOV, EB
  摘要：The robustness to nonnormality of the F test for model adequacy depends essentially on the distribution of repeated trials over the support points of the design. The influence of the regression design matrix on robustness is more limited.
• THE REDUCED MAJOR AXIS OF A BIVARIATE SAMPLE AI翻译
  作者：CLARKE, MRB
  摘要：In situations such as allometry where a line is to be fitted to a bivariate sample but where an asymmetric choice of one or another variable as regressor cannot be made, the reduced major axis is often used. Existing tests of the slope of this line, particularly between samples, are not sufficiently accurate in view of the scarcity of the material to which such methods are often applied. Alternative test statistics are suggested and some of their properties derived from a computer implementati...
• ADDITIONAL INFORMATION ON SIGNIFICANCE VALUES FOR DURBIN C+, C- AND C-STATISTICS AI翻译
  作者：JOHANNES, JM; RASCHE, RH
  摘要：Exact tabulated values for Durbin''s c+, c- and c statistics are extended, and modified forms of the statistics are presented to facilitate use of the statistics in large samples.
• 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.
• LINEAR PREDICTION IN THE FACTOR-ANALYSIS MODEL AI翻译
  作者：ISOGAWA, Y; OKAMOTO, M
  摘要：For the problem of linear prediction in the factor analysis model, the h heuristic predictor suggested by Scott (1966) and the unbiased predictor proposed by King (1969) are mathematically identical, respectively, with the optimal biased predictor and the optimal unbiased predictor due to Lawley and Maxwell (1973).
