Two new Weibull probability plotting papers are presented. Their use is explained, and they are compared with other Weibull papers...

Since the publication of the four-part article on multivariate methods [1, 2, 3 and 4], this author has received many requests to prepare a paper at the same level on regression. This paper will briefly review the estimating and testing procedures commo..

Conventional probability plotting paper can be readily augmented to permit graphical determination of quantiles for order statistics. An example of such paper is given for the normal family of distributions. The use of order statistic quantiles in testi..

The object of this paper is to review and illustrate the concept of statistical tolerancing and the methods which are applicable to assigning component tolerances. The approach is primarily theoretical, but the theory is that which is useful in practice..

The analysis of means (ANOM) is an alternative to the analysis of variance (ANOVA) for examining fixed effects. It was formalized by E.R. Ott and further developed by E.G. Schilling. This paper provides an extended table of factors needed for ANOM for s..

Likelihood functions provide a convenient and useful means of summarizing the numerical information that the data has to offer about a parameter or a set of parameters. This paper introduces the concepts of likelihood and likelihood functions and uses t..

This paper considers the operating characteristic (OC) properties of two-level skip-lot sampling plans. Skip-lot plans were initially introduced by Dodge and later were investigated extensively by Perry. Three two-level plans are considered here. These ..

This paper argues that multivariate statistical analysis of operating data may provide the necessary information and insight needed to adequately control many of the complex industrial processes that do not lend themselves to rigid deterministic feedbac..

This paper introduces and develops a new concept in statistical sampling, Price Adjusted Single Sampling (PASS) with linear indifference. The basic purpose in developing this inspection technique is to eliminate the process of rejecting lots, a common p..

The use of a residual analysis prior to the performance of statistical tests upon experimental data is recommended as a routine procedure. This paper describes (a) the calculation of residuals from data resulting from a variety of experimental designs; ..

Many industrial processes include a circular multiple-head machine which runs continuously and which permits a variety of adjustments to the parts of the machine. This paper illustrates several methods for investigating various types of differences by e..

Incomplete failure data consisting of times to failure on failed units and differing running times or unfailed units are called multiply censored. Data on units operating in the field, for example, are usually multiply censored. Presented in this paper ..

It is known that regression results can be misleading when the predictor variables (x's) are highly correlated (nonorthogonal). The objective of this paper is to present some guidelines for deciding when the correlations among the x's are so large that ..

Regression analysis has become a very popular method for analyzing existing plant and research data. The existence of correlations among the independent variables is recognized as a major pitfall in the proper interpretation of such data. This paper out..

The purpose of this expository paper is to explain the construction of exact truncated sequential tests for the mean of the normal distribution when the standard deviation is know. Exact one-sided and approximate two-sided tests are given. The parameter..
