Fourth International Workshop on Matrix Methods for Statistics Montreal, Quebec, Canada: Saturday, July 15-Sunday, July 16, 1995 The Fourth International Workshop on Matrix Methods for Statistics will be held in Montreal, on Saturday, July 15 and Sunday, July 16, 1995, the weekend immediately following the Joint Annual Meeting of the Statistical Society of Canada (SSC) and the Institute of Mathematical Statistics (IMS). This Workshop is co-sponsored by the International Linear Algebra Society (ILAS). The Workshop venue, Le Centre Sheraton Hotel (1201 Boulevard Rene-Levesque West, Montreal), is the same as for the Joint Annual SSC/IMS Meeting that precedes it. The purpose of this Workshop is to stimulate research and, in an informal setting, to foster the interaction of researchers in the interface between matrix theory and statistics. This Workshop will provide a forum for statisticians and mathematicians working in the areas of linear algebra and matrix theory to become better informed of the latest developments and newest techniques and to interchange ideas with researchers from a wide variety of countries. Contributed papers are welcome! Submit a one-paragraph abstract, in English or French: no more than 10 lines please! If at all possible use plain TEX, emTEX, LATEX or Microsoft Word and send the abstract by e-mail (as a regular ASCII text file or in Binhex) to George Styan at the address below. All abstracts should arrive by 15 May 1995. Registration fees are: ILAS, IMS or SSC Members: C$50/US$45; non-members: C$65/US$60; students: C$15/US$15. These rates are valid Through May 15, 1995. A late surcharge of C$15/US$15 will apply thereafter for all non-student participants. Requests for more information concerning the scientific program, as well as any organizational questions, should be directed to: George P. H.
