Prediction and Forecasting
“Prediction is concerned with estimating the outcomes for unseen data. (…) you fit a model to a training data set, which results in an estimator f^(x) that can make predictions for new samples x.” (Döring 2018)
“Forecasting is a sub-discipline of prediction in which we are making predictions about the future, on the basis of time-series data.” (Döring 2018)
