Antitubercular activity of Sulfathiazole Derivitives series were subjected to Quantitative Structure Activity Relationship (QSAR) Analysis with an attempt to derive and understand a correlation between the Biologically Activity as dependent variable and various descriptors as independent variables. QSAR models generated using 28 compounds. Several statistical regression expressions were obtaine...

In this study, the concept of relative membership degree is proposed to investigate grey optimal cluster evaluation. Besides, the correlation coefficient between sample observation value and standard eigenvalue is used to reflect the similarity degree of evaluation objective and each cluster centre. Based on those mentioned above and concept of relative membership degree, an optimized grey clus...

• In the most difficult case where the number of observations n ≡ 3 (mod 4), high Defficiency of certain chemical balance weighing designs under completely symmetric covariance matrix of errors is shown. It is also proved that D-optimal design may depend on the values of the correlation coefficient.

The conventional starch determination (employing precipitation, filtration, re-dissolution, colour development) is compared with a simplified direct colorimetric procedure, which is readily automated. The reproducibility is better than 3%, with a correlation coefficient of 0,87 between the two methods.

This paper describes the specifications and results of UMCC_DLSI system, which participated in the Semantic Textual Similarity task (STS) of SemEval-2013. Our supervised system uses different types of lexical and semantic features to train a Bagging classifier used to decide the correct option. Related to the different features we can highlight the resource ISR-WN used to extract semantic relat...

We calculated the correlation between the state-level quality measures and prices to address the question “is higher quality associated with higher prices?” The correlation coefficients are presented in Table 1. A positive correlation implies higher quality measures occur where prices are higher. A negative correlation implies the quality measures are relatively lower where prices are higher an...

In this paper, we proposed a novel method for evaluating intonation of an English utterance spoken by a learner for intonation learning by a CALL system. The proposed method is based on an intonation evaluation method proposed by Suzuki et al., which uses “word importance factors,” which are calculated based on word clusters given by a decision tree. We extended Suzuki s method so that multiple...

Let X = {Xn}n≥1 and Y = {Yn}n≥1 be two independent random sequences. We obtain rates of convergence to the normal law of randomly weighted self-normalized sums ψn(X,Y) = n ∑ i=1 XiYi/Vn, Vn = √ Y 2 1 + · · ·+ Y 2 n . These rates are seen to hold for the convergence of a number of important statistics, such as for instance Student’s t-statistic or the empirical correlation coefficient.

objective(s): reliability measures precision or the extent to which test results can be replicated. this is the first ever systematic review to identify statistical methods used to measure reliability of equipment measuring continuous variables. this studyalso aims to highlight the inappropriate statistical method used in the reliability analysis and its implication in the medical practice.   m...

chickpea (cicer arietinum l.) is a native crop of asia which is grown worldwide including iran.in this study,different selection criteria including correlation,regression and path analysis were used to improve yield.the experimental design was split plot with rcbd replicated four times in which three sowing dates (5 january,4 february,and 5 march) were used in main plots and four genotypes;two ...
