36285 - Memory problems might occur with a large number of BY groups If you are processing a large number of BY groups in PROC RELIABILITY then memory problems may occur. Sparse data (few failures or events) in some or all of the BY groups exacerbates this problem. http://support.sas.com/kb/36/285.html, 20KB |

8493 - Incorrect output is produced when using the THRESHOLD option in PROC RELIABILITY The RELIABILITY procedure allows a fixed threshold, g, to be specified for the Weibull, lognormal, and loglogistic distributions. The procedure computes estimates for the distribution parameters using Y = T - g as the ... http://support.sas.com/kb/8/493.html, 19KB |
