Psychometrically Equivalent Bisyllabic Word Lists for Word Recognition Testing in Taiwan Mandarin
… (-5 to 40 dB HL) in increments of 5 dB. Logistic regression was used to include 200 words with the steepest logistic regression slopes in four psychometrically equivalent word lists of 50 words each with eight half-lists of 25 words each. Digital recordings of the psychometrically equivalent …

Muscle Strength, Motor Units, and Aging
… covariance (ANCOVA) that tested heterogeneity of regression slopes (moderation analysis). Results: The test-retest analysis yielded moderate relative reliability and moderately-high absolute reliability. A positive linear relationship was found between MUNIX and strength in the elderly, but not in …

Psychometrically Equivalent Cantonese Bisyllabic Word Recognition Materials Spoken by Male and Female Talkers
… from -5 to 40 dB HL in 5 dB increments. Logistic regression was used to determine the words with the steepest logistic regression slopes. The 200 words with the steepest slopes were then formulated into four lists of 50 words and eight half-lists of 25 words. The mean psychometric slope value at …

A Comparison Of Ordinary Least Squares, Weighted Least Squares, And Other Procedures When Testing For The Equality Of Regression
<p>When testing for the equality of regression slopes based on ordinary least squares (OLS) estimation, extant research has shown that the standard F performs poorly when the critical assumption of homoscedasticity is violated, resulting in increased Type I error rates and reduced statistical power …

Biology and control of the lesser mealworm: Alphitobius diaperinus, a structural pest in poultry houses
… of permethrin proved to be ineffective. Regression slopes from topical application studies reveal that tetrachlorvinphos may be the material of choice against A. diaperinus because there is less chance of the lesser mealworm developing resistance to tetrachlorvinphos than with either …

Performance Intensity Functions for Digitally Recorded Japanese Speech Audiometry Materials
… across 10 different intensity levels. A logistic regression was used to obtain regression slopes for each of the 240 words. The 200 bisyllabic words with the steepest slope were selected for inclusion in the final CD. Four lists of 50 words each and eight half-lists of 25 words each were created …

Psychometrically Equivalent Digital Recordings for Speech Audiometry Testing in Mandarin Chinese: Standard Mandarin Dialect
… and word lists were analyzed using logistic regression. For speech reception threshold testing, 24 Mandarin Chinese trisyllabic words with steep psychometric function slopes were selected. Their intensities were adjusted to match the mean subject pure-tone average of 3.0 dB HL. The mean …

A study of the predictive validity of the Kenya certificate of primary education examination : application of hierarchical linear models
… A moderate linear relationship, parallel regression slopes, and the extent to which the selected moderator variables influenced the KCPE-KCSE relationship indicate that KCPE is a moderately valid predictor of success in secondary school.

QSAR studies of surfactant toxicity to Daphnia magna.
… water sharing between hydrocarbon chains, the regression slope was para"el to but distinct from that of LAS. This indicated that either FAES substances were not acting as by the same mode of action as LAS or that modification of the log P calculation was required. Further studies of the …

Detecting and Evaluating Therapy Induced Changes In Radiomics Features Measured From Non-Small Cell Lung Cancer to Predict Patient Outcomes
… were defined as relative net changes, linear regression slopes, and end of treatment feature values. Features were then evaluated in univariate and multivariate models for overall survival, distant metastases, and local-regional recurrence. In general, the delta-radiomics features were not …

Pedogenesis, weathering processes, and elemental distribution along a soil climosequence in the southern Piedmont
… North Carolina, and Georgia soils, with regression slopes decreasing from north to south. Clay content levels off at higher Fed values for Alabama soils, indicating that i) steady-state conditions are approached as pedogenic clay formation reaches some intrinsic, self-limiting threshold …

Allelopathy and autotoxicity studies and allelochemicals isolation and identification of alfalfa (Medicago sativa L.)
… greater allelopathic effects than root extracts. Regression slopes of various top extracts showed significant variation with respect to germination percentage. Velvetleaf extracts were the most inhibitory, while large crabgrass extracts had the least allelopathic effect on alfalfa. Aqueous …

The influence of cultivar and environment on the relationship between flour protein content and grain yield in wheat
… be adjusted to a common HI. This was because the regression slopes of protein contents on HIs differed between cultivars. This was due mainly to the cultivar x N interaction for HI but not for protein content. Protein content increased with each increment of N application. The response of grain …
