CLOSED - THANKS to all customers for the last few years

I'm trying to have a little snooze in my basket and all i'm getting is rant rant rant from a boozed up student moaning about easy peazy tests! How is a poor little pup supposed to dream about girls and bods with all that going on!!!

I see your point JS, good to have a moan now and again. :-)

Ok, I've picked out one of the easy ones... give me a bit of time to type it out... you will have 20 minutes from the time posted, and no cheating...

Yeah JS but don't forget to give us the answers on the blackboard at the front like you had?

Consider the following regression model:

Yt= α +t + Ut

where Ut = εt(α0 + α1U^2t-1)^0.5


(a) Show that the variance is ht = α0 + α1U^2t-1

(b) Explain how such a model might be estimated in practice


Sorry haven't figured out how to get a formula to look correct in here!

Right 20 minutes starting now... Good Luck!

GD I only said they might as well put the answers up :-)

And less of the boozed up student... I'm a student - therefore I'm poor.

I do one of those for breakfast every morning! let's have something with guts?

Go on then GD... every dog has his day :-)

I hate to say this but i think i'm getting very 'Klutey' of late! and for those that have no idea what i'm on about - forget it!

The answer is.....


...4

You know... I reckon The True Klute would have got that right...

I'll give you a clue... the Ut is basically an ARCH(1) model :-)

My brain hurts....and I'm only reading the comments....
;>)

Poochy might still have Klutey's email. It would be fun to send that to him and hear his response.

Silly question, JS, but what subject are you studying?

JS, Such a simple question makes me and bunny laugh. We want something to really test our mathematic skills?.

Ok bunny lets go out back for a long fag.

LOL Poochy, and the sun is finally shining here today!

Priscilla, Yes i still have K's email. Poochy would like to give you a little kiss for Easter x

Bunny, try sitting through a couple of hours of it every day :-)

Cilla, nothing that passes those gorgeous lips of yours can possible be silly... Economics and Business Finance

GD... especially for you (and I'm sorry its so easy):

Differentiate with respect to w the following utility function:
alnw^-3.5b - where a and b are constants

:-)

I prefer integration JS.

and with that poochy leaves the coffee house to sit outside in the evening sunny breeze to sip a bods. ta ta.

See you around and have a good Easter GD

Hello, anyone in?

Have a great weekend everybody. See you Tuesday-ish.. ;-)

Hello Socs and Bye! Have to dash I'm afraid....
Have a great weekend and don't forget to pick up your easter egg!!
