Dear fellow landscapers, I need fine sand to plant a few flowers. I put a few 5 cm rocks into my kitchen blender and started it on high grate. The blender seems to buzz and vibrate, but I don't see any sand coming out of it, just smoke. I bet your model is still around replication number 10 or so. One way to try to gauge how much time you need on your full data set is to figure out how the problem scales. Run it with 100, 200, 500 and 1000 observations by 100, 200 and 400 replications (-set rmsg on- or use -timer-); fit a power model log( time ) = a + b log( sample size) + c( number of bootstrap replicates), and -predict- how things will look like for 100,000 observations. I did something of that kind timing my -confa- package in http://stata-journal.com/article.html?article=st0169 (may be that's something that the authors of computationally intensive packages should do). When people ask me about -confa- and show me their syntax with 50+ variables, I just [ palm face ] it. PS. I have MP4 -glamm- running for the 6th day doing multiple imputations on a model with two latent factors and a data set with 400 observations. And another -glamm- problem with 350,000 observations running for the 12th day. Sometimes, you have to be patient.
