The purpose of this thesis is to derive and compare asymptotic
performances of certain tests of independence, interchangeability
and equality of the distributions of_ratios Y/X for positive variates
and Y with joint c.d.f. H(x,y) of particular forms. Three bivariate
families, Morgenstern, Plackett, and Moran, are considered which permit
marginal c.d.f.'s...
Birdsfoot trefoil (Lotus corniculatus L.) is a popular perennial, non-bloating forage legume used for pasture, hay and silage throughout the temperate regions of Europe, Asia Minor, North Africa and North and South America. It is regarded as the most morphologically and biochemically variable species in the genus. Research investigating the...
The contributions of Korean immigrant-owned fashion companies (KIOFCs) are increasing in the U.S. fashion industry. This study explored more deeply how KIOFCs can obtain competitiveness in the fiercely competitive fashion market. Specifically, this study 1) described the prominent characteristics of KIOFCs in the Los Angeles area, 2) investigated the multidimensional...
The purposes of this study were to examine the experiences of African American female students attending urban community colleges, to gain further understanding of how they interpret the meaning of persistence, and to identify the factors that affect their persistence. African American women attending community college in Los Angeles were...
Exposure to urban outdoor air pollution is ubiquitous and low birth weight represents an important health disparity in the United States. While previous research suggests that exposure to outdoor air pollutants are associated with term low birth weight, few studies have evaluated the effects of multipollutant outdoor air exposures or...
The problems of constructing prediction and tolerance intervals
were considered for Weibull regression models. On the extreme value
distribution scale, the models have the linear form y = Xβ + σ z ,
=NM
where y is the transformed random response vector, X is the nxq
matrix containing values of...
The purpose of this study was to determine the
effects of a six-week career planning dropout prevention
program on the self-concepts and academic achievement of
at-risk middle school students in an inner-city public
school environment. The research population consisted of
1,434 students (grades seven, eight and nine) attending an
inner...
