You can build a linear regression equation with the help of this. It helps to calculate the Y values easily. When the value of the Significance F is not greater than 0.05, the independent variables have a statistically significant relationship with the dependent variable. Significance F is a crucial term to find the output of your model whether it is statistically significant or not. If you divide the MS of regression by the MS of Residual, you’ll get the F-test. It tests the overall significance of the regression model. Mean Square is mainly the mean of the square of the variation of an individual value and the mean value of the set of observations.į: F refers to the Null Hypothesis. The higher value of the Sum of Squares refers to a higher variation in the values or vice-versa. The Sum of Squares is the square of the difference between a value and the mean value. SS: SS (Sum of Squares) symbolizes the good to fit parameter. It can be calculated using the df=N-k-1 formula where N is the sample size, and k is the number of regression coefficients. It is the second part of the analysis result.ĭf: df expresses the Degrees of Freedom. Observations: The number of iterations in the data model.ĪNOVA means Analysis of Variance. It shows the average distance of data points from the Linear equation. A smaller number for the regression equation provides increased certainty in its accuracy and reliability. Standard Error: It shows a healthy fit of Regression Analysis. The adjusted R-squared is a metric that takes into account the number of independent variables included in the model. The regression analysis model is a good fit for the data, as almost 99% of the values fall within the predicted range.Īdjusted R Square: The value of R^2 is used in multiple variables Regression Analysis instead of R square. In our example, the value of 0.997 is pretty good. An R-squared value of more than 95% is generally regarded as a good fit for a regression model. It indicates how well the data model fits the Regression Analysis. R Square: It symbolizes the Coefficient of Determination.
