8/28    Did any of you take Stat 205A? Do you have to know measure theory in
        advance?
        \_ I have taken a UCLA equivalent.  Usually people recognize a lot of
           engineering folks want to take such a class, so the usually teach
           it in a way that doesn't require you attenting a measure theory
           class (they review the measure theory that's needed).  I wouldn't
           be surprised if they do this at Berkeley also. -- ilyas
           \- "know measure theory" can "cover a lot of area" ... this may
              be easier to answer if you mention something about your back-
              ground. "the only upper div math class i have taken is 104"
              vs. "i have done lots of math, just not that much analysis/
              integration theory etc." i had a good background in measure
              theory but not much background in stat so i had to relearn a
              lot of vocab [e.g. the "mapping" from the lebesgue density
              lot of vocab [like the "mapping" from the lebesgue density
`             thm to the martingale density thm]. BTW, if you dont have a
              Giant Math Brain, one thing about grad math/physics classes:
              often people sort of work sort of collaboratively so it is
              helpful if your friends or officemate is in the class ... having
              to do 20hr problem set by yourself can really suck ass.

              \_ I did applied math as undergrad and took many upper div
                 stat classes but haven't done much real analysis beyond
                 math 104. -op
                 \-i'd say go for it. a lot of applied stat people dont have
                   the greatest background in the deep math of sigma algebras.
                   \_ I will. I am still worried though that prof. Pitman
                      tried to discourage me by saying that ppl who haven't
                      had measure theory usually struggly in this course.

                      \- a friend of mine [ucb stat phd, now teaches biostat]
                         came in to stat from EE so she took 104 and 105.
                         if you have taken a lot of math classes i think
                         that more than offsets doing just 105 ... what class
                         is pitman recommending anyway? 105 is the only one
                         that seems to fit the niche. he isnt saying you
                         need 202ab is he. of course i used to get phone calls
                         at 3am from this friend asking "what is a banach
                         space" ...

                         calls from this friend asking "what is a banach
                         space" ... actually come to think of it i also got
                         a 3am phone call from her because she "heard a strange
                         sound" and was hiding in her closet, but that is
                         another matter.
                         \_ He says it's ok to take 205A now but ideally
                            everyone should take 105 before 205A. Another
                            possibility is to take the new Stat 204
                            which sounds like Stat 205A 'lite'.
                            \- i knew almost nobody who took 105 ... it isnt
                               always offered even is it? i think you figure
                               it all out in 202ab ... doesnt the ROYDEN book
                               cost like $5000 now? BTW, i think GREEN/PAPA
                               RUDIN is a useful book to have around.
                               The POWER of the RIESZ REPRESENTATION THEOREM.
                         \_ Sounds like she was trying to pick up on you.
                            I hope you banged her.
