We will use the Pearson Correlation Coefficient to determine the two assets’ correlation. This method, one of the most popular for measuring the linear relationship between two variables, will help us understand the relationship between two stocks: Facebook and Amazon, in our case. The average M...

The correlation coefficient is applied to finance and economics to track and better understand data. While data trends and statistical analysis often go untracked by small businesses; investment banks, financial services companies, and even the federal reserve of the United States use the correlation c...
dwill be zero; and it is easily seen that the correlation coefficient in question is the mean value of (d+ d+ + d) divided by the product of the square roots of the mean values of (dd) and of (d+ + d); if we denote the mean value of dby m, this becomes 29m/30m, or 29...
Correlation coefficient can also be calculated using Excel CORREL function. It’s syntax is CORREL(array1, array2). array1 and array2 represent the series of x and y values. Example The following table shows the monthly close data for SPDR S&P Oil & Gas Explore & Prod. (ETF) (XOP) (...
Definition:The Pearson correlation coefficient, also called Pearson’s R, is a statistical calculation of the strength of two variables’ relationships. In other words, it’s a measurement of how dependent two variables are on one another. ...
The correlation coefficient is a value that indicates the strength of the relationship between variables. The coefficient can take any values from -1 to 1. The interpretations of the values are: -1:Perfect negative correlation. The variables tend to move in opposite directions (i.e., when one...
The degree of correlation is measured by acorrelation coefficient, such asPearson’sr.The value of the correlation coefficient always ranges between 1 and −1, and it serves as an indication of the strength and the direction of the relationship between variables. ...

How do I calculate the correlation coefficient? The correlation coefficient formula is: r = (n*sumXY - sumX*sum Y)/sqrt{(n*sumX^2 - (sumX)^2)*(n*sumY^2 - (sumY^2))}.The terms in that formula are: n = the number of data points, sumXY is the sum of the product of the ...
