while negative covariance means returns move in the opposite direction. Covariance is usually measured by analyzing standard deviations from the expected return, or we can obtain it by multiplying the correlatio
The correlation coefficient, or r, always falls between -1 and 1 and assesses the linear relationship between two sets of data points such as x and y. You can calculate the correlation coefficient by dividing the sample corrected sum, or S, of squares for (x times y) by the square root...
Applying this formula to our two stocks: 1result_cov<-cov(AAPL,MSFT,method="spearman")23result_cov45[1]29.921056 We have a positive covariance of 29.92. Correlation in R Programming We can calculate correlation of these two vectors using the cor() function in R programming. It takes the sa...
