답변:KSSV2017년 7월 6일 I have a data set that contains spectral scans at different wavelengths, another data set with concentrations of compounds at different time points. I want to run a correlation between the spectral scan and the concentration of compounds. ...
Now i can plot these sets easily for each component of Y into one plot, so I can see the differences. What I would like to do now is calculate the correlation coefficient to see how well these data sets match. My problem is this: I can only correlate them, if the vectors of Y ...
The correlation coefficient is a statistical calculation that is used to examine the relationship between two sets of data. The value of the correlation coefficient tells us about the strength and the nature of the relationship. Correlation coefficient values can range between +1.00 to -1.00. If t...

This function returns the correlation coefficient between two parallel data sets (XrangeList1andXrangeList2). The correlation coefficient determines the relationship between two data sets. Syntax @CORRELATION (SKIPNONE | SKIPMISSING | SKIPZERO | SKIPBOTH,XrangeList1,XrangeList2) ...
Pearson's correlation, a well-established statistic for calculating the association between two variables, has been applied to measure the coexpression of TFs and target genes in both RNA-seq and scRNA-seq data sets. Being symmetric in its arguments, this correlation does not predict the direction...
This value actually determines the linear correlation between two sets of data, often denoted byrsorⲣ. ThePearsonProduct Moment Correlationdetermines the linear relationship between continuous variables. The general expression ofPearson correlationis: ...
