Sorry I do not get your question... This post rises in the context where I built a model, and let's say two predictors are significant, but one of these predictors has a parameter estimate value lower than the RMSE value.
A basic question about the comparison of RMSE value and parameter estimate. I got the point that RMSE value and parameter estimate are not correlated to each other and that a parameter estimate smaller in value than the RMSE value can still be significant for the model.
But still, I...
