The estimates of genotypic correlation coefficients in general were higher than their corresponding phenotypic correlation coefficients indicating strong inherent association among the traits. The seed yield per plant had significant and positive association with number of primary branches plant-1, number of secondary branches plant-1 , number of pods plant-1 , number of seeds plant-1 , biological yield plant-1 , seed yield (kg/ha) harvest index and 100-seed weight at both genotypic as well as phenotypic levels.

The kinetics of the reversible thermal unfolding, irreversible thermal unfolding, and reductive unfolding processes of bovine pancreatic ribonuclease A (RNase A) were investi-gated in NaCl/Pi solutions. Image parameters including Shannon entropy, Hamming distance, mutual information and correlation coefficient were used in the analysis of the CD and 1D NMR spectra. The irreversible thermal unfolding transition of RNase A was not a cooperative process, pretransitional structure changes occur before the main thermal denaturation....

Essays in Macroeconomics and the Economics of Higher Education In single-MSA regressions of test scores on student characteristics, the above arguments imply greater attenuation of the peer group coefficient in MSAs with less stratified schools. As choice is positively correlated with stratification, this produces a tendency toward larger estimated coefficients (i.e. less bias toward zero) in high-choice MSAs.

Phân tích tương quan (Correlation) là kỹ thuật rất thường dùng trong thống kê y học nhằm khảo sát mối liên quan giữa 2 biến số đo trên cùng các đối tượng thông qua hệ số tương quan (correlation coefficient). Có nhiều loại hệ số tương quan (HSTQ) nhưng bài này chỉ trình bày hệ số tương quan r của Pearson (Pearson r correlation coefficient). Pearson r là số đo mối liên quan tuyến tính của 2 biến số, và được sử dụng khi 2 biến số thuộc thang đo lường tỉ số hoặc thang khoảng. ...
