The C and C++ standards do not specify the order of evaluation for function arguments. This can lead to subtle portability problems. As I explained in my column last month (“As Precise As Possible”), ...

We present and compare several algorithms for evaluating Jacquet's Whittaker functions for SL(3,ℤ). The most suitable algorithm is then applied to the problem of evaluating a Maass form for SL(3,ℤ) ...

Many statistical models arising in applications contain non- and weakly-identified parameters. Due to identifiability concerns, tests concerning the parameters of interest may not be able to use ...
