I just started stats, and i missed the first few days. Im kind of confused on what the who and what are. Can someome maybe explain to me..in simple terms?

Also, can someone explain what we use log for?

Id really appreciate it!

If you're wondering why there's been no replies it's because:

1. Your first question makes absolutely no sense.

2. Your second question is too broad to give a simple and short answer to (I assume you want to know what log is used for in statistics ....?) Especially when your mathematical background is a complete unknown.

Suffice to say, when you get to the part of your course where log gets used, then you'll know the answer.

Does your course have a recomended/set text? If so read the introduction

and or the first chapter overview material.

If not Browse through the early seactions of this

prerequisites of your course and they will be covered when you need them.

If it pre-calculus is a pre-requisite then you should already have covered

what you need to know.

Actually I think it does make sense and isn't nearly as broad a field as you took it to be. I'm not competent to answer the question, but if memory serves W is something called the "maximum likelihood" function, and we take the logarithm of that for some reason which my memory fails me on. I think that is what the op assumed we knew. (I ran into this in a graduate lab ages ago when we were talking about the derivation of formulas. I never really understood the derivations, but I could use my notes to derive the correct formulas anyway.)

Yes, that had crossed my mind (the maximum likelihood stuff etc., NOT your graduate lab days ) but then I thought - first few days of the course, I don't think so ...... No idea of stats or maths background, could be opening a can of worms here, a thread that would die the death of a thousand cuts. Not to mention create huge angst and worry in the mind of the member.

The thing is that log could crop in many many different ways - at both an advanced level and an elementary level. It might even have been a review of pre-calc .......

Additional data: http://www.mathhelpforum.com/math-he...ity-model.html.

Pr(the W's means maximum likelihood function| additional data) = 0.001, perhaps?

Actually I'm curious to know what the question*really*was asking .....
