This R-squared calculator, or squared correlation (or coefficient of determination, calculator, calculates the measure of how close the data points of a data set are to a given regression line.
Instructions: Use this calculator to compute the adjusted R-Squared coefficient from the R-squared coefficient. Please input the R-Square coefficient (R2)(R2), the sample size (n)(n) and the number of predictors (without including the constant), in the form below: ...
This calculator will compute the 99%, 95%, and 90% confidence intervals for an R2 value (i.e., a squared multiple correlation), given the value of the R-square, the number of predictors in the model, and the total sample size.
The R squared value ranges between 0 to 1 and is represented by the below formula: R2= 1- SSres / SStot Here, SSres: The sum of squares of the residual errors. SStot: It represents the total sum of the errors. Always remember, Higher the R square value, better is the predicted ...

R squared (R2) or coefficient of determination is a statistical measure of the goodness-of-fit in linear regression models. While its value is always between zero and one, a common way of expressing it is in terms of percentage. This involves converting the decimal number into a figure from...
