Which Test To Use?

Sun, 07 Feb 2016 01:39:35 GMTShort version: 2-3 IVs (date, individual, compartment), repeated-measures(compartment), 20 DVs, non-parametric.
Hello,
I have 4 subjects...Short version: 2-3 IVs (date, individual, compartment), repeated-measures(compartment), 20 DVs, non-parametric.

Hello,

I have 4 subjects that were tested 16 times. However, possible changes across time or individuals are not the subjects of the experiment, so would it be appropriate to consider the number of participants 64?

During each of the 64 trials, subjects were presented with six compartments simultaneously. Numerous (about 20) different measures were taken across these six compartments.

Finally, the data is not normal, and would need a non-parametric test.

Which test(s) would be appropriate for between compartments 1-6?

My initial thinking is that a Friedman test for each variable would work: 64 rows, 6 columns. Though, I would be running 20 of them, unless there is a 20-way equivalent.

Thanks!

The study indicates that they use Cox regression for survival analysis
Results indicate that for group differences in depressive episodes the hazard ratio =0.38 95% and confidence interval is 0.19-0.75; p<0.006

I have read up on this and cannot seem to understand what it means. Is there any way you could explain this in simple terms. Thanks X

Sat, 06 Feb 2016 04:05:47 GMTHi!

In above histogram I know 65% of samples have (0 - 3 minutes) service time or 21% of samples have (3 - 6 minutes) service time but I can not interpret connected points which are distinct with arrowhead! Could you please guide me to find out them?
