The output of all of these procedures is a list of nodes that belong in the optimal set, along with a measure of fit – the extent to which they satisfy the objective. Remove There are two criteria for crippling a network that you might use to decide which nodes to remove. Fragment. Distance. Observe Version 1 of KeyPlayer only has one option under Observe, which is called Reach. The key option in this program is the number of steps to allow.

Honeycutt, and Wendy Luke It’s not as easy as you think. Three association consultants—a former CEO new to the consulting biz, a research and publications specialist, and a human resources expert with 18 years of consulting experience—talk about striking out on their own and share their advice about the challenges inherent in making the leap from association management to consulting. Plus, several other ASAE & The Center Consultant Members share their tips, as well.

Introduction and Caveats This page serves, as one might expect, to allow other researchers to access some of the data analysis tools I've developed in the S language. The implementation of S used here is that of the R Statistical Computing Environment , rather than the common alternative of S-PLUS ; the intrepid could doubtless port these routines from one flavor of the language to the other, however.
