More specific about whether knowing what I'm doing is GPU-enabled. Jan 15 asked MATLAB GPU-enabled function? Dec 6 comment Naive Bayes where posterior almost always equals prior (in MATLAB)Dave, I edited the question to suggest I think this was the solution. Thank you. Even so, I realize I am unclear as to how categorical data is interpreted in naive Bayes: you discuss the 256 partitions, with (I think) a = 2 (classifying, say, "yes" or "no") and m=n=p=q=2 if we assume only 2 unique attributes within each category. I thought naive Bayes would simply assign a probability to each variable within each category and would ignore a variable to be classified if there was no training example. Can you clear this up or point me toward a good reference? Dec 6 revised Naive Bayes where posterior almost always equals prior (in MATLAB)Added "Edit" section to follow-up from Dave's questions. Dec 6 asked Naive Bayes where posterior almost always equals prior (in MATLAB) Oct 22 comment Gauss' proof that "the best estimate for a random variable is the average"I think this is correct, @whuber. If you paste your comment as an answer I can select it. In the meantime, I ordered Stewart's 1987 translation of the Gauss work you mention; I will post page numbers and confirm the answer once I make my way through it. Thanks to all. Oct 20 comment Gauss' proof that "the best estimate for a random variable is the average"Thank you, @IrishStat. I will see how this question develops elsewhere before selecting a solution, but regardless this is a very helpful link. Thank you! Oct 20 comment Gauss' proof that "the best estimate for a random variable is the average"Thanks, @whuber, for the helpful clarification. I believe the original (quoted) author's intent was the former option; i.e., in the instance in which there is no sample data, and "average" is meant as "expectation." As for "best," I'm sure that would be outlined in the actual proof, but I think what the original (quoted) author meant was that this result should (at least) not be inferior to any other formulation. Again, thanks.
