Coefficient of Variation. In statistics, the ratio of the standard deviation of a series of data points to the expected return. In investing, the coefficient of variation is used to measure the volatility (represented by the standard deviation) to the expected return on an investment.A lower coefficient of variation indicates a higher expected return with less risk.n investing, the coefficient of variation is used to measure the volatility (represented by the standard deviation) to the expected return on an investment.
The square of the coefficient of multiple correlation can be computed using the vector of correlations between the predictor variables (independent variables) and the target variable (dependent variable), and the correlation matrix of inter-correlations between predictor variables.It is given by.ith more than two variables being related to each other, the value of the coefficient of multiple correlation depends on the choice of dependent variable: a regression of on and will in general have a different than will a regression of on and.
