Correlation coefficient values range between -1 and +1. When there is a positive correlation coefficient, both the x and y values increase. If there is a negative correlation coefficient, x increases when y decreases or x decreases when y increases. If the correlation coefficient is +1, two ...
According to this table, considering one of the estimated values as zero and the remaining equal to the actual values results in a decrease in VAF and NSE. Similar to the correlation coefficient, the lowest values of the NSE and VAF (i.e., ˗0.67 and ˗0.48, respectively) are ...
Real-world applications of correlation coefficient in data analysis Correlation coefficient is widely used in data analysis across a range of industries and fields. Here are a few examples: In healthcare, correlation coefficient is used to analyze the relationship between patient outcomes and various ...
The most common correlation coefficient, generated by the Pearson product-moment correlation, measures the linear relationship between two variables. However, in a non-linear relationship, this correlation coefficient may not always be a suitable measure of dependence. The possible range of values...
In the correlation coefficient, r falls in the range of +1.0 to -1.0, depending on the strength of the relationship between the two variables. An r of 0 indicates that there is no relationship between the two variables. An r of +1.0 describes a positive correlation between two variables, ...

Thecorrelation coefficientis how you'll typically get information about the correlations (negative or otherwise) between different things. It's given as a number ranging from -1.0 to +1.0. A coefficient of +1.0 is a perfect positive correlation, indicating that two assets move in perfect unison...

Low, intermediate and high sTILs were observed in 62.9%, 18% and 19.1%, with a median score of 20 (range 0–96) (Table2). The inter-rater reliability defined by intra-class correlation coefficient was 0.87 (95% C.I. 0.73–0.94) in 100 samples. We observed no significant difference be...
