Abstract While fiducial inference was widely considered a big blunder by R.A. Fisher, the goal he initially set—‘inferring uncertainty of model parameters on basis observations’—has been continually pursued many statisticians. To this end, we develop new statistical method called extended Fiducial (EFI). The achieves leveraging advanced computing techniques while remaining scalable for data. Extended involves jointly imputing random errors realized in observations using stochastic gradient...
