Overview
Nowcasting is often defined as the prediction of the present, the very near future and the very recent past.
-rjd3nowcasting provides helps to operationalize the process of nowcasting. This first version can be used to specify and estimate dynamic factor models. It also includes the concept of “news” similar to the Nowcasting plugin for the Graphical User Interface of JDemetra+ v2.
