We’ve demonstrated how to do a backward forecast, which is a prediction for an observation that falls before the start of the sample data. The key step was reversing the chronicle order of the input time series before the start of the analysis.
What is a backwards EXtrapolation?
The basic idea in the Backward EXtrapolation (BEX) method is to construct the function describing the reduction in CPS due to the dead time effect, by artificially imposing a growing dead time on the signal, and then extrapolate the resulting function back to zero.
What is the opposite of forecasting?
In statistics and data analysis, backcasting can be considered to be the opposite of forecasting; thus: forecasting involves the prediction of the future (unknown) values of the dependent variables based on known values of the independent variable.
