# Coefficient of Determination

Coefficient of determination serves as a measure in statistical analysis model. It determines how well a model explains and predicts the future outcomes. An another measure of how well the least squares equation performs an predictor of y.

The values of R$^{2}$ lies between 0 and 1 and higher the R$^{2}$ the more useful the model. Coefficient of determination is symbolized by r$^{2}$ because it is square of the coefficient of correlation symbolized by r.

Useful in trend analysis and serves as an important tool in the determining the degree of linear correlation of variables in regression analysis.It can also be used as a guideline to measure the accuracy of the model.
