Arthur, I was the FBI's "senior personnel statistician" for 11 years as a govt. employee then 2 1/2 yrs more as their contractor on the same Federal class action racial discrimination law suit. They had lost the case and I was hired in view of the monitoring provisions of the class action settlement. I wrote about 180 technical reports on that and related topics, most of which were considered admissible in Federal court as evidence. I also wrote declarations that were admitted into evidence and rebuttals of the other side's expert statistician's analyses of the same body of personnel data, that also were used by the FBI's team of litigators.
To respond to your questions:
-- Expert statistician or expert personnel research statistician or technical advisor might do as titles
-- The Daubert case against a pharmaceutical firm is considered the standard, I believe, for determining qualifications of expert witnesses
-- In my work, I turned to several statistically oriented books dealing with how courts considered statistical evidence in this arena. Among them were: Connolly. Peterson, Connelly "Use of Statistics in Equal Employment Opportunity Litigation" (Law Journal Press, updates issued annually, representing critiques by a member of the bar of that year's EEO cases, selected for using some form of statistical analysis/model/methodology.) In general, the book or collection of annual updates is filled with citations of how the Court found in various cases and their reasoning. There's also Levin and Kaye, "Statistics in the Courtroom" and the many articles of Dr. Joseph Gaswirth on applying statistical methods to EEO issues. The first book I mention would have a great many citations of circuit and Federal courts' statistical reasoning (such as the cases dealing with what alpha level is suitable, whether or not 2 standard deviations is enough of a discrepancy between groups to represent statistical significance, why they threw out a case because a model was underspecified, etc.)
-- After my government retirement, I was paid as a contractor by the FBI in the same roles as before. This was considered a sole source contract that the Contracts Office worked out with me. I submitted a monthly (quarterly also was available) invoice for the number of hours I worked,my fee for those hours, and a general summary of what I did during that time. I also maintained my own listing of reports I had written during that monthly period. I was a certified Federal contractor, and had filed to be listed in that way. I think the database is called CCR. I would think that someone worked as a technical advisor to a Federal judge would need to be listed in that database of Federal contractors.
-- I might say that other federal agencies heard of me through my FBI agency contacts, and so one of them called me for some specific advice. I provided that at no cost, as a favor.
You may gain some more information about the personnel statistician/technical advisor role by contacting the Federal Judicial Center, located near Union Station.
Hope this information helps and good luck,
