Methodology for Testing Homogeneity of Variances
(University of Texas at Arlington, 1979-02)
Suppose random samples are drawn from each of n populations with unknown means and variances. Developing procedures to test the claim that the population variances are equal (homogeneity of variances) has frequently been ...
Pitman-Closeness Efficiency of Estimators of Reliability with Application to the Exponent/Al Failure Model
(University of Texas at Arlington, 1977-10)
When there are available several point estimators of component or system reliability, it would be of interest to compare such estimators through some "closeness to the true value of reliability" criteria. Along these lines, ...
On the Determination of Critical Values for Bartlett's Test
(University of Texas at Arlington, 1979-06)
The exact critical values for Bartlett's test for homogeneity of variances based on equal sample sizes from several normal populations are tabulated. It is also shown how these values may be used to obtain highly accurate ...
On the Relative Behavior Of Estimators of Reliability/Survivability
(University of Texas at Arlington, 1978-05)
Based on a decomposition of mean absolute error, a twofold technique is introduced whereby a pairwise comparison of point estimators of reliability/survivability can be made. Given two such estimators, the method examines ...
Comparison of Point Estimators of Normal Percentiles
(University of Texas at Arlington, 1977-08)
There are available several point estimators of the percentiles of a normal distribution with both mean and variance unknown. Consequently, it would seam appropriate to make a comparison among the estimators through sums ...
