In addition, I believe that with your minimum sample size of 25 (n=25), this would represent only about 1/10th of 1% of the 2007 X5 population of 23,798, and would not be statistically significant, even at the absolute lowest confidence levels i.e. in order to achieve a confidence level of .95 or a margin of error of .05 with a probability of .50, your sample size would need to be > 300. I'm viewing this thread as a free site advertising medium for you. I understand that you have, "a long time horizon and no investors to pay off". That makes sense to me since as long as this thread exists, it's free advertising for your site. I'll leave this thread active until you respond, but if you want the thread to remain active, you will need to give our members a way to access the information free of charge. Otherwise, this thread represents zero benefit with respect to information for our members, and that is the purpose of our forum . Now, we can always discuss your becoming a forum sponsor. Please send me a PM for further details .
