1. For Mon 16 Feb, …

1. For Mon 16 Feb, work through Exercises 2.1, 2.4, 3.1. The nerve impulse data set (of size n = 799 measurements) for the latter exercise may be found here: http://www.stat.ncsu.edu/sas/sicl/data/nerve.dat . Use both AIC and BIC to assess the exponential, the Gamma and the Weibull models, perhaps supplemented by one of your own choice or construction. Also, present point estimates and 90% confidence intervals for the probability that a random nerve impulse needs more than 0.333 seconds.

2. Sections, 2.6, half of 2.7, 2.10 are defined as cursory curriculum, but the "bootstrap-AIC" of Section 2.7 is considered as belonging to the ordinary curriculum. Section 2.8 is also inside, but I choose to postpone going through that material until we start on Ch 5 (also to get us to Ch 3 more quickly).

For Mon 16 Feb I plan to go through Section 2.9 plus relevant parts of 2.7 and 2.10.

3. I have uploaded the R script file "com2b", which deals with four models for the n = 141 Roman era Egyptian life-times.
