Here, we propose a novel method, Tight Nearest-neighbor prediction correlation Test (TNT), to determine whether two continuous variables are nonlinearly correlated. TNT first use the values of one variable to c
quite erroneously, correlation between two random variablesXandYis interpreted as causation, i.e.,XcausesY. Take the example of AC sales (X) and frozen yogurts sold (Y). If a positive correlation is found (say,r= 0.8), would that imply thatXcausedYor vice-ver...
The correlation is the important operation of bivariate data. To find the relationship between the variables, we use correlation. By looking at the direction of the graph or by looking at the value of correlation coefficient we can interpret the relationship between them....
Therefore, the two variables influencing the selection of scenarios are the importance factor (Ie) and ground acceleration (SS). The four scenarios addressed in this study, along with the corresponding Cs values, are shown in Table 2. The seismic response coefficient (Cs) values corresponding to...
Drake93acknowledged the great uncertainties (ACCs = 200 – 50,000,000) and inferred that there were probably between 1000 and 100,000,000 ACCs in our galaxy. Other scientists used different estimates for these variables, resulting in a range of estimated ACCs from < 100 to several ...
Canonical correlation analysis (Hotelling, 1936) determines the relationship between variable sets from two domains of measurement. Given X and Y of dimensions p and q from the same set of n observations, the first CCA mode is reflected in a linear combination of the variables in X and another...
MFA is a form of correlation analysis, and not a hypothesis test of causality, but can analyze three or more groups of variables (Abdi et al., 2013). The correlation between different variable categories is measured by the RV coefficient, which is a measure of the similarity between square ...

The next step, after all this information is fed to the algorithms, is to use machine learning techniques such as ridge regression—a methodology for learning relationships between two variables—in order to quantify the similarities between companies. This points to another advantage of AIPGS. Beyo...
