Calculating the Pearson correlation coefficient can be complicated but software makes it much easier. You can use several methods to calculate correlation in Excel.

We introduce a novel parametrization of the correlation matrix. The reparametrization facilitates modeling of correlation and covariance matrices by an unrestricted vector, where positive definiteness ...

We extend the autocorrelation-based approaches currently used in standards to full correlation-matrix-based approaches in order to identify correlation between both spatially adjacent and non-adjacent ...

Abstract: We consider a complex-valued L × L exponential correlation matrix. Such a matrix has unit diagonal elements; each lower off-diagonal element is the correlation coefficient raised to the ...

In Excel spreadsheets, complex formulas are difficult to enter without making mistakes. Microsoft Excel’s LAMBDA() function can make such errors easier to find.

The components of eigenvectors of the complex cross-correlation matrix distribute in the complex plane, allowing the recognition of lead-lag relationships between components based on the difference in ...
