Explain the nominal and operational ways of defining a variable. Select the better response: the response variable in a linear correlation and regression problem is recorded on this measurement scale: a. categorical, b. ordinal, c. quantitative. ...
Correlation and regression models were also performed to test the predictive power of lexical and syntactic complexity features. It was found that lexical complexity, when compared to syntactic complexity, is a stronger predictor of L2 writing quality. The impact of text types, examination prompts ...
The highest negative correlations (R > − 0.5) were observed between S with both Ca and P. Distinguishing between tusks from Asian and African elephants. Of the 24 elements measured, only three, copper (Cu), Cl, and Pb exhibited no difference between Asian and African tusks...
Other than canonical computational pipelines, machine learning and deep learning models have been recently applied for A-to-I prediction. However, the application of these models in A-to-I calling also faces challenges. On the one hand, the manual and knowledge-based nature of feature extraction ...

2006; Smith and Epstein 1971). A correlation between the proportion of maize in the feeding ration and the δ13C content of the tail switch hairs has been demonstrated in some studies (Hammes et al. 2017; Schwertl et al. 2005, 2003; Wittmer et al. 2010). The previous studies used ...
Linear and nonlinear quantitative structure activity relationship models for predicting the inhibitory activities of sulfonamides toward different carbonic anhydrase isozymes were developed based on multilinear regression, principal component-artificial neural network and correlation ranking-principal component analysis...
Before feature selection, the radiomic features were normalized, and only features with an intraclass correlation coefficient (ICC) greater than 0.80 were retained. First, we employed the maximum correlation and minimum redundancy (mRMR) method to reduce dimensionality by eliminating redundant and ...
Study 1 focuses on similaritiesand correlations within the classes, and Study 2 focuses on the performance of thepairs in the two classes in an analogy task. These two studies are complementedby a third study that uses distributional vectors containing information about theinternal make-up of the...
Since the two specifications are observationally equivalent, including the same set of variables, the econometric diagnostics of the regression equations are used to differentiate between the two of them. Six statistical criteria are compared: serial correlation, heteroscedasticity, specification tests, fit...
