Use this calculator to compute the R square adjusted (adjusted coefficient of determination) value for your regression equation

R square

Enter the observed R square (coefficient of determination) as obtained after running regression. E.g. if R square is 90.54%, enter 90.54 (i.e. without the % sign)

Sample Size

Enter the number of observations in the sample or the sample size

Number of independent predictors

Enter the number of independent predictors in the model

Number1

R square adjusted cannot be calculated

For the given sample size and number of predictors, R Square Adjusted cannot be calculated. Kindly check and enter correct numbers

R square adjusted

Calculated R Square Adjusted (adjusted coefficient of determination).
A negative value indicates that the predictors to sample size ratio is high (i.e. a lower sample size was considered) or it can also indicate the presence of correlated predictors.
