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 ...
Offshore Oil/Gas Lease Bidding and the Weibull Distributions
(University of Texas at Arlington, 1980-03)
It is the purpose of this paper to study the use of the Weibull distribution as an acceptable model for the distribution of the bids on a lease. A multi-sample test procedure of the Weibull-bids hypothesis will be given ...
On the Discrimination Between the Lognormal and the Weibull Distributions With Applications to Offshore Oil/Gas Lease Bids
(University of Texas at Arlington, 1980-05)
The competitive sealed bids on an individual offshore oil and gas lease are often assumed to follow a lognormal distribution (Brown, 1969). However, under the lognormality assumption there are known discrepancies between ...
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 ...
