Question

Define term correlation. Computer correlation coefficient between x and y

Answer 1

The correlation of X and Y is the normalized covariance: Corr(X,Y) = Cov(X,Y) / σXσY . The correlation of a pair of random variables is a dimensionless number, ranging between +1 and -1

Answer 2

The correlation of X and Y is the normalized covariance: Corr(X,Y) = Cov(X,Y) / σXσY . The correlation of a pair of random variables is a dimensionless number, ranging between +1 and -1

Answer 3

The correlation of X and Y is the normalized covariance: Corr(X,Y) = Cov(X,Y) / σXσY . The correlation of a pair of random variables is a dimensionless number, ranging between +1 and -1

Answer 4

The correlation of X and Y is the normalized covariance: Corr(X,Y) = Cov(X,Y) / σXσY . The correlation of a pair of random variables is a dimensionless number, ranging between +1 and -1

Answer 5

The correlation of X and Y is the normalized covariance: Corr(X,Y) = Cov(X,Y) / σXσY . The correlation of a pair of random variables is a dimensionless number, ranging between +1 and -1
