Calculating the correlation coefficient is time-consuming, so data is often plugged into a calculator, computer, or statistics program to find the coefficient.

Regression imputation is commonly used to compensate for item nonresponse when auxiliary data are available. It is common practice to compute survey estimators by treating imputed values as observed ...

Correlation is a statistical measure of how two securities move in relation to each other. Investors use correlation to diversify their portfolios and hedge against risk.

Negative coefficients indicate opposite direction of movement in most cases. The other key result is the correlation of the two. Regression statistics will typically include an R-squared value.
