I have 5400 and more data points. It is very difficult to see anything in the graph with so many (SAS won't actually plot that many although I am working on changing the defaults).
How do you do a hetero test given this. To make things worse at least one of the hetero test makes an assumption of the data being singular which was not met and thus might not be useful (I don't think this means the data is not hetero, just that the test does not work).
