[R] Revolutions Blog: July Roundup

[Frank Harrell]

David, as always this is a terrific roundup.  I note in passing that the "big
data" logistic function rxLogit used on the 1B observation dataset
(impressive run time!) inappropriately used the t distribution for testing
the coefficients in the logistic model [at least if the notation used is any
clue].  It should have used the normal distribution.

Cheers,

Frank
