Use predicted R-squared to determine how well a regression model makes predictions. This statistic helps you identify cases where the model provides a good fit for the existing data but isn’t as good at making predictions. However, even if you aren’t using your model to make predictions, ...

Adjusted R-Squared This isa modified versionofR-squaredthathas been adjustedforthe number of predictors in the model. It isalways lower than the R-squared. Theadjusted R-squaredcanbe usefulforcomparing the fit of different regression modelstoone another. In this example, theAdjusted R-squared is...
How to Interpret the Result of Excel Multiple Regression Regression Statistics: In theRegression Statisticsportion, we see values for some parameters.

However, you also need to be able to interpret "Adj R-squared" (adj. R2) to accurately report your data.Statistical significanceThe F-ratio tests whether the overall regression model is a good fit for the data. The output shows that the independent variables statistically significantly predict ...
risk of the fund/portfolio relative to that of a benchmark (e.g., a specific market or index). It has taken its share of inspiration from the widely accepted Sharpe Ratio; however, it has the significant advantage of being in units of percent return, which makes it easier to interpret....
How should I interpret a 'root mean squared log error' (rmsle) score? I'm used to scores which reflect the percentage of variance explained such as the adjusted r squared, so the rmsle doesn't really mean anything to me. My first attempt at the bike sharing competition gave me pretty...
Meanwhile, the low variability model has a prediction interval from -30 to 160, about 200 units. Clearly, the predictions are much more precise from the high R-squared model, even though the fitted values are nearly the same! The difference in precision should make sense ...
In this post, I show how to interpret regression models that have significant independent variables but a low R-squared. To do this, I’ll compare regression models with low and high R-squared values so you can really grasp the similarities and differences and what it all means. ...
How Do You Interpret a Coefficient of Determination? The coefficient of determination shows the level of correlation between one dependent and one independent variable. It's also called r2or r-squared. The value should be between 0.0 and 1.0. The closer it is to 0.0, the lesscorrelatedthe dep...
