#EXCEL 2016 DATA ANALYSIS REGRESSION HOW TO#

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. 0 indicates that there is no correlation at all between the variables.-1 indicates a strong negative correlation between the variables.1 indicates a strong positive correlation between the variables.The bigger positive the value, the stronger correlative the relationships are. Multiple R: Multiple R indicates the correlation between variables. We will try to explain the simple regression analysis result that we have performed. However, understanding the output may seem difficult if you do not know what the terminologies mean. Performing regression analysis is quite easy.
