Five variable selection methods are available. The simplest method (and the default) is SELECTION=NONE, for which PROC PHREG fits the complete model as specified in the MODEL statement. The other four ...

Java is an object-oriented programming language, but there’s more to Java than programming with objects. This tutorial is the first of several introducing non-object-oriented features and syntax that ...

Mathematical programming discriminant analysis models must be normalised to prevent the generation of discriminant functions in which the variable coefficients and the constant term are zero. This ...

Flexible main methods and anonymous main classes would help students write basic programs much more concisely and reduce the ceremony of writing simple programs. Java would become easier for students ...

In this paper three methods are derived for approximating $f$, given its Laplace transform $g$ on $(0, \infty)$, i.e., $\int^\infty_0 f(t) \exp(-st) dt = g(s ...
