This example shows how you can use PROC LIFEREG and the data step to compute two of the three types of predicted values discussed there. Consider a continuous random variable Y, and a constant C.

A random variable that can take only a certain specified set of individual possible values-for example, the positive integers 1, 2, 3, . . . For example, stock prices are discrete random variables ...

A new algorithm is presented for simulating stable random variables on a digital computer for arbitrary characteristic exponent $\alpha (0 < \alpha \leq 2)$ and skewness parameter β (-1 ≤ β ≤ 1). The ...
