Question 1

Most discussions on model prediction says that you should focus on error metrics, like RMSE, MSE, MAE or MAPE. Some even argue that r-squared can be low in a good model. However, I can't think of a ...

Question 2

In my models, R2 in training and test sets are close to each other, but in RMSE, MSE, MAE of some models, these are very different? what is the reason Is there a solution?

Question 3

...

Question 4

I'm trying to predict some variables for MOF's (from a scientific paper) using the Random Forest model in Phyton, but the value of R2 is negative (different from the paper, which was positive). I ...

Question 5

We can compute real or population correlation(rho) by square-root of 1 minus R-squared.Is this a correct interpretation? Does population correlation mean a real correlation measured as square-root of ...

Question 6

I was running a Linear Regression with Wooldridge dataset named GPA2, which is found on Python library named wooldridge. I tried two linear regressions. The first: ...

Question 7

I was reading the paper "Consistent Individualized Feature Attribution for Tree Ensembles" by Scott Lundberg et al. and cannot understand how the calculation for the $R^2$ works here - see ...

Question 8

I am solving a Multiple Linear Regression problem and judging the model by looking at R-square and Adjusted R-square metrics. In recent iteration which are yielding desired coefficients directionally ...

Question 9

I have a high-dimensional space, say $\mathbb{R}^{1000}$, and I have samples $y_1, \ldots , y_n \in \mathbb{R}^{1000}$ and $\hat{y}_1, \ldots , \hat{y}_n \in \mathbb{R}^{1000}$. Would $$ R^2 = 1 - \...

Question 10

If for example I have the value of RMSE can I calculate the $R^2$? And vice versa if I have the value of $R^2$ can I calculate the value of RMSE? I have all predictions, dataset, training set, and ...

Question 11

I'm trying to build model for this datatset (Age prediction): The input image has the shape: 3, 128, 128 and the predicted labels (ages) range between 20 to 51. I ...

Question 12

I am training an XGBoost model, xgbr, using xgb.XGBRegressor() with 13 features and one numeric target. The R2 on the test set ...

Question 13

I'm trying to create a linear regression model with use of PolynomialFeatures. But when I evaluate it, I get really strange scores. I know that R^2 can be applied to this model and I think I've trying ...

Question 14

Does the appliance of R-squared to non-linear models depends on how we calculate it? $R^2 = \frac{SS_{exp}}{SS_{tot}}$ is going to be an inadequate measure for non-linear models since an increase of $...

Question 15

I am trying to determine which model result is better. Both results are trying to achieve the same objective, the only difference is the exact data that is being used. I used ...
