Out-of-sample prediction is the acid test of predictive models, yet an independent test dataset is often not available for assessment of the prediction error. For this reason, out-of-sample performance is commonly estimated using data splitting algorithms such as cross-validation or the bootstrap...
Shrinkage estimators for prediction out-of-sample: se- lection of estimators and predictive inference. unpublished manuscript, 2015.N. Huber and H. Leeb. Shrinkage estimators for prediction out-of-sample: Conditional performance. Commun. Statist. - Theory Methods, 42(7):1246- 1264, 2013. doi:...
Motivated by the low bias of the leave-one-out cross-validation method, we propose a computationally efficient closed form approximate leave-one-out formula ALO for a large class of regularized estimators. Given the regularized estimate, calculating ALO requires a minor computational overhead. With ...

We now consider the matrix \(\varPi \) of the out-of-sample predictions of the models to be three dimensional with \([\varPi ]_{ijk}\) to denote the out-of-sample prediction (i.e, when the example was held-out during training) on the i-th example, of the j-th configuration,...
While most of the empirically well-known predictive variables fail to generate out-of-sample predictability, we document a significant out-of-sample prediction in forecasting ahead one-year and, to a lesser extent, one-quarter future excess returns, using a combination forecast of variables. We ...

I have 100period time series data and want to do 'rolling regression' from t1~t50. After that, by doing 'out of sample prediction', using the estimates, want to compare them with raw data.(from t51~t100)From your question it looks like you want to be able ...
