Mach12, 2020 GW Tech Report Archive 1968-1993 The Department of Statistics maintained a TR Archive from 1960-2019, but as of today it is not publicly available. I have copied all of my TR's and some of those of my students from 1968-1993 and they appear in this archive. Some already appear elsewhere in this website. For papers 1993 and later see the TRLIST. .........Directory Contents............................
