StoTree is software tool for the formulation and solution of continuous-time Markov models of medical interventions, implemented in the Excel spreadsheet environment. Although the popular package TreeAge from TreeAge Software Inc. has a more extensive set of tools, StoTree is a free alternative that can handle the same types of models in a continuous-time framework. Like Precision Tree from Palisade Corporation, StoTree is an Excel addin that can implement both decision trees and Markov models.

This document presents strategies you can use to write an effective project report, and prescribes an organizational structure for writing such a report. Four fundamental objectives for writing an effective project report are cited, namely, demonstrate your familiarity with the problem, establish your modeling expertise, maximize reader insight, and minimize reader effort. Writing strategies and organizational structure are meant to secure these objectives.

Josh McDowell's book Evidence That Demands a Verdict has been described as an authoritative defense of Christianity and a masterpiece of Christian apologetics that provides scholarly, intelligent, well-grounded answers to questions about the Christian faith. Here I report on my investigation of McDowell's claims.
