Back to Philly

Today and tomorrow, I am attending a conference in Wharton in honour of Larry Brown for his 70th birthday. I met Larry in 1988 when visiting Cornell for the year—even using his office in the Math department while he was away on a sabbatical leave—and it really does not feel like that long ago, nor does it feel like Larry is any close to 70 as he looks essentially the same as 22 years ago! The conference is reflecting Larry’s broad range of research from decision-theory and nonparametrics to data analysis. I am thus very glad to celebrate Larry’s birthday with a whole crowd of old and more recent friends. (My talk on Rao-Blackwellisation will be quite similar to the seminar I gave in Stanford last summer [except that I have to talk twice as fast!])
