Description
I need at a minimum four paragraphs. One on each of the following subjects:
1) Frequency analysis of multinomial outcomes with an explanation of the "likelihood" that results fall within 1, 2, or 3 standard deviations of the mean.
2) Transition matrices from one state to another.
3) Likelihood ratio tests...this is more a comparison of expected probability to observed as a rough intro to contingency tables
4) Chi Squared testing of multinomial distributions.
This job posting is a bit unusual for me. Normally, I hire people to do things that I don't know anything about (like graphic design). But I actually have a PhD in Statistics and have decades using these techniques in industry and government. My problem is that I can't seem to write in a way that is technically correct AND easy to understand.
The ideal proposal will somehow demonstrate the ability to bridge this gap.
If you feel my description was a bit vague, it is. I have graphs and images that I will share once a writer is selected. But for now, I just need someone who knows what I am talking about and can explain it.

Hello. Is this task available? Thanks.
Chuck W.31 Mar 2018Thank you for asking. Yes, this project is still available. There have been a number of questions about the specifics of the job and I am allowing time for people to receive my responses. I anticipate making a decision on the posting Monday or Tuesday of next week.

Hi Chuck,
Quite a challenging proposal you've got here, but to make a decent quote, it is essential to know your audience, in other words to establish their level of knowledge.
Please let me know..

Chuck W.31 Mar 2018Thank you for this question, it draws out an important point which I had not refined earlier.
The target audience is non-technical.
The key concept which I am attempting to bridge between professional statisticians and non-technical users of statistical analysis is the notion of "fail to reject the null hypothesis".
The website in question is a public watchdog site to confirm that various lottery gaming commissions are actually conducting "fair" games. The problem is that games cannot be perfectly "fair" because that makes them highly predictable. Therefore, the gaming commissions have to allow some deviation from "fair" results but not so much that they become predictable "unfair".
Finding the right words to express these concepts to a non-technical audience is why I need help.
