i never get help for any questions on this website.
Do you have a specific question? Do you state the problem clearly? Do you write in clear language (capitalize first letter of first word of sentence, use periods, keep text message garble out of the question) and is the question stated clearly? Finally, do you show what you have done with the question and tell why you don't know what to do next. We try to answer all questions within a few hours. Please try again if you can answer all of the above yes.
You are asking advanced statistics questions, we do not currently have a volunteer for those. When you finish your course, you are most welcome to join in our volunteer ranks.
Thanks.
