st: how do I generate fake time series data?

[David Airey <david.airey@Vanderbilt.Edu>]

Dear List,

I would like to generate data like a nested repeated measures ANOVA but 
with time series data:

Treatment1 (Fixed)
	Unit1 (Random)
		Subunit1 (Random): time1 time2 time3 ... time100 ... etc
		Subunit2
		...
	Unit2
		Subunit3
		Subunit4
		...
	...
Treatment2
	Unit1
		Subunit1: time1 time2 time3 ... time100 ... etc
		Subunit2
		...
	Unit2
		Subunit3
		Subunit4
		...
	...

I am having trouble generating the time series aspect of the data with 
the desired correlation in it. How do you do it in Stata?! I want to 
investigate what happens when I ignore unit information:

Treatment1 (Fixed)
		Subunit1 (Random): time1 time2 time3 ... time100 ... etc
		Subunit2
		Subunit3
		Subunit4
	...
Treatment2
		Subunit1: time1 time2 time3 ... time100 ... etc
		Subunit2
		Subunit3
		Subunit4
	...


-Dave
