In this talk we describe a method for combining a measure of association from several 2xC contingency tables. The columns in the 2xC tables are assumed to be ordered and the method uses the weighted least squares methodology of Grizzle, Starmer and Koch (1969). The method uses a transformation of the gamma statistic, a statistic proposed for the analysis of ordered contingency tables by Goodman...

The DRM Consortium carried out a high-power field trial of the DRM+ system [G1] in the FM band inthe central Scotland area, centred on the city of Edinburgh, in the United Kingdom during Januaryto May 2011. The DRM Consortium members contributed their expertise and equipment to the trialto enable the system to be tested in a real commercial environment with a wide variety of...

Exact logistic regression has become an important analytical technique, especially in the pharmaceutical industry, since the usual asymptotic methods for analyzing small, skewed, or sparse data sets are unreliable. Inference based on enumerating the exact distributions of sufficient statistics for parameters of interest in a logistic regression model, conditional on the remaining parameters, is...

Pressures from consumers concerned with sow well-being in gestation stalls have encouraged producers to consider how to transition from individual gestation stalls to pens in existing buildings. The aim of this study was to evaluate the performance and well-being of sows in pens that were retrofitted from stalls (2.1 by 0.55 m). Large pens (5.5 by 7.3 m) housed 26 sows and small pens (5.5 by 1....

In clinical trials, a dose response study is often conducted to investigate the relationship between increasing dosage and the effect of the drug under study. The Cochran-Armitage trend test is commonly used to study the underlying trend. This paper summarizes various SAS procedures, including PROC FREQ, PROC MULTTEST, and PROC LOGISTIC, which perform the trend test when the response is binary....

The objective of this study was to determine the effects of dietary Trp supplementation on mixing-induced aggression and the associated stress, and on reproductive performance in gestating sows. After weaning, sows were mixed in pens with electronic sow feeders on concrete-slatted floors. Each pen housed 21 ± 2.8 sows, with approximately 2.7 ± 0.43 m(2)/sow of floor space allowance. Multiparous...

Electrical-Discharge machining (EDM) stands for highly accurate and very sophisticated metal shaping. The physical process takes advantage of electric field effects between two electrodes, a tool and a workpiece. Material is removed by sequences of electrical discharges. The electrically efficient gap width, which is determined among other parameters by the electric conductivity of the gap and ...

In order to assess the reliability of a given characterization of a subject it is often necessary to obtain multiple readings, usually but not always from different individuals or raters. The degree of agreement among the various raters gives some indication as to the consistency of the values. If agreement is high, we feel more confident the ratings reflect the actual circumstance. If agreemen...
