NNH talk update (November 12, 2007).

Last year, I gave a talk for PharmaIQ about continuous monitoring of the number needed to harm. I want to update this talk for a second audience in December. Here's the London talk:

• Stats #71: Control charts for continuous monitoring of the number needed to harm

I have some newer material

• Stats: Tracking adverse events during kidney biopsy, Part 2 (April 5, 2007)

as well as a second unpublished example. I also want to provide some R code to produce the graphs shown in these examples.
