TheInstitute of Statisticians was a Britishprofessional organization founded in 1948 to protect the interests of professionalstatisticians.[1] It was originally namedThe Association of Incorporated Statisticians Limited, but this was later changed.[2] The institute was formed after theRoyal Economic Society prevented a 1947 extension to theroyal charter of theRoyal Statistical Society which would have allowed it to carry out examinations.[1]
The Institute of Statisticians attempted to obtain a royal charter of its own in 1978 and this led to discussions with theRoyal Statistical Society about a possible merger. Talks foundered over disagreement on how to arrange the various membership categories. Within a few years, however, the talks were revisited, and on 1 January 1993, the two organisations merged, becoming simply theRoyal Statistical Society.[1]
From 1950 the institute published ajournal, first calledThe Incorporated Statistician (ISSN 14669404) then renamedThe Statistician (ISSN 0039-0526) in 1962, before being subsumed into theJournal of the Royal Statistical Society asSeries D upon the merger in 1993.[3][4]
