Anscombe recruited established Yale statisticians from other disciplines to build the statistics department's graduate programs.

Anscombe wrote a classic text, Computing in Statistical Science through APL, in 1981; it remains in print.

In computerizing the analysis of statistical data, he drew on his exp[ertise in probability and variance.

He cautioned strongly against misinterpreting and misusing the computer models he developed. In a famous 1973 paper, he showed how one equation could easily fit four different sets of data.

Anscombe attended Cambridge University on a scholarship, earned a mathematics degree in 1939 and a master's degree in 1943. During World War II, he worked on mathematical aspects of firing rockets.

He lectured at Cambridge and Princeton before being recruited for Yale by Tjalling C. Koopmans, an economist who later won a Nobel Prize.

Boisvert went to Tokyo 20 years ago from his native Canada to run a coffee shop owned by the family of his wife, Yuriko Hiraguri.

In 1984 he joined a consulting firm to teach employees how to use personal computers.

In 1993, he set up IIKK, Japan's first authorized commercial Internet service provider. The next year he set up his own provider, Global OnLine (GOL). GOL became one of Japan's leading ISPs and pioneered many areas of electronic commerce.

Boisvert sold GOL in 1999 and set up a venture capital company, CTR Ventures.

"He never lost touch with the hacker crowd, with the engineers whomake things work," said Thomas Caldwell, a journalist writing a biography of Boisvert.

Boisvert and a friend became lost in Los Angeles early in the morning on Sept. 30. They stopped along a highway and were studying a GPS map in the car when a robber approached them and demanded money.

Although both men complied, the robber fired once, killing Boisvert.
