Plant breeders traditionally have estimated genotypic and phenotypic correlations between traits using the method of moments on the basis of a multivariate analysis of variance (MANOVA). Drawbacks of using the method of moments to estimate variance and covariance components include the possibility of obtaining estimates outside of parameter bounds, reduced estimation efficiency, and ignorance o...

The present investigation examined auditory evoked potential (AEP) recovery functions in both high-risk (HR, N = 23, mean = 22.3) and low-risk (LR, N = 27, mean = 23.0) males. A series of binaural auditory stimuli, with randomly interposed interstimulus intervals (ISIs) of 0.5, 1.0, and 10.0 s, were used to elicit the N1 and P2 components of the AEP. Scalp potentials were recorded from the 19 e...

Latent Growth Curve Models (LGCM) are discussed as a general data-analytic approach to the analysis of change. Conventional, but popular, methods of analyzing change over time, such as the paired t-test, repeated measures ANOVA, or MANOVA, have a tradition, which is quite different from the more recently developed latent growth curve models. While the former originated from the idea of variance...

Data are presented on two computerized tests of everyday verbal learning: Paired associate learning of First-Last Names (FLN), and the Grocery List Selective Reminding Test (GLSRT). MANOVA and multiple regression analyses demonstrated that performance on FLN and GLSRT was most strongly related to age, with significant secondary associations found for gender, with females performing better than ...

The impact of ethnicity on word fluency measures, i.e., the FAS (Benton & Hamsher, 1976) and Animal Naming (AN) (Spreen & Strauss, 1991) tests, was explored. The groups included: White (n = 200), Black (n = 200), and Hispanic (n = 200) veterans. Multivariate analysis of variance (MANOVA) revealed significant main effects for FAS and AN total scores both before and after covarying for income, ed...

the current study aims at the comparative analysis of the religious copping, optimism, and social physique anxiety between the disabled and the normal people.  as for the methodology of this comparative analysis, 60 gorgani people, 30 disabled and 30 normal people, were chosen through systematic random sampling in 1395 taken from the names of those disabled who were registered in the welfare or...

This study investigated attachment, maintenance behaviors, and stress in long distance (LDR) and geographically close (GCR) romantic relationships. Data was analyzed from participants (N = 473) who were in a serious romantic relationship and who completed two attachment measures, two maintenance behaviors measures, and a perceived global stress measure. A multivariate analysis of variance (MANO...

This study of English as a second language (ESL) reading textbooks investigates cohesion in reading passages from 27 textbooks. The guiding research questions were whether and how cohesion differs across textbooks written for beginning, intermediate, and advanced second language readers. Using a computational tool called Coh-Metrix, textual features were compared across the three levels using M...

BACKGROUND The complex mechanism of nicotine dependency makes it challenging to evaluate dependence or progress towards dependence. The aim of this study was to estimate nicotine dependence levels and identify determinants of dependence among Chinese rural-urban migrants. METHODS Multi-stage systematic sampling was used to select 4,198 rural-urban migrants aged 18 years or older from three me...
