It is often of interest to estimate partial or semipartial correlation coefficients as indexes of the linear association between 2 variables after partialing one or both for the influence of covariates. Squaring these coefficients expresses the proportion of variance in 1 variable explained by the other variable after controlling for covariates. Methods exist for testing hypotheses about the eq...

OBJECTIVE The objective of this study was to evaluate the intra-examiner and inter-examiner reproducibility of paraspinal thermography using an infrared scanner. MATERIALS AND METHODS The thermal functions of a commercially available infrared scanner (Insight Subluxation Station®) were evaluated for clinical reliability. Two practicing clinicians conducted the measures on 100 subjects. Intra ...

In the present research, three different architectures were investigated to predict the coefficients of the Daubert and Danner equation for calculation of saturated liquid density. The first architecture with 4 network input parameters including critical temperature, critical pressure, critical volume and molecular weight, the second architecture with 6 network input parameters including the on...

AIM to evaluate the test-retest reliability of the Indonesian version of OABSS and its correlation with other validated assessment tools for OAB. METHODS eligible patients aged 18 years with established OAB were instructed to complete 3-day micturition diaries and the OABSS, International Prostate Symptom Score (IPSS) and Patient Perception of Bladder Condition (PPBC) on two separate visits: ...

I find the use of a correlation coefficient a dangerous symptom. It is an enemy of generalization, a focuser on the “here and now” to the exclusion of the “there and then.” Any influence that exerts selection on one variable and not the other will shift the correlation coefficient. What usually remains constant under such circumstances is one of the regression coefficients. If we wish to seek f...

The assessment of reliability and construct validity for scales used to evaluate families is potentially limited because standard coefficients are not computed appropriately using the combined responses for family members due to their possible intra-familial correlation. In this paper, we describe and demonstrate the use of linear mixed modeling to compute generalizations of such coefficients f...

OBJECTIVE FFQ are commonly used to rank individuals by their food and nutrient intakes in large epidemiological studies. The purpose of the present study was to develop and validate an FFQ to rank individuals participating in an ongoing Prospective Urban and Rural Epidemiological (PURE) study in Chile. DESIGN An FFQ and four 24 h dietary recalls were completed over 1 year. Pearson correlation...

The extended Gini is a family of measures of variability which is mainly used in the areas of finance and income distribution. Each index in the family is defined by specifying one parameter. The higher the parameter, the more weight is attached to the lower portion of the cumulative distribution. In this paper we list and investigate the properties of the equivalents of the correlation coeffic...

Speech is the fundamental way of communicating with one another. It simply refers to transmission of messages. In case of speech production the information is transmitted in the form of analog waveform that can be transmitted, recorded or decoded. A number of algorithms for speech recognition have been proposed. In this paper, we have suggested an innovative approach of speech recognition. We h...

The test of homogeneity for intraclass correlation coefficients has been one of the active topics in statistical research. Several chi-square tests have been proposed to test the homogeneity of intraclass correlations in the past few decades. The big concern for them is that these methods are seriously biased when sample sizes are not large. In this thesis, data driven approaches are proposed t...
