The first copies of Stata 10 arrived on Monday while I was out of town. The copies for our lab and my Mac arrived on Wednesday around noon. At 3pm, a client comes into consulting who is analyzing MRI data on several different probes over 300 time points. She has been doing non-linear modeling separately for each of the probes, however, it is the same exponential model in each case. The client wants to test whether the parameters estimated by the exponential models are statistically different or not. This turns out to be a perfect job for the new nlsur (non-linear seemingly unrelated regression) command. Ten minutes of work and it is up running. Its fun to play with new toys.
