I can't compliment too much in a shoe polishing way
Otherwise, people will think I was acting and don't believe in me.

LOL
I don't have a large data set to provide me a good normal distributi ...

well the it can be a t-distribution if sample size is smaller than 30
we are not looking for compliements here... it's statistics... LOL

OMG, you know about t-distribution with N

perhaps you are the one who has bad memories - i m business major
that said, i failed stat as one of the core subject
was at the door being expelled because we could not afford to fail a core
i re took and scored C- which is bare pass

We can list out a lot of factors of a beauty and give weighting.
Then gives score of each factor.

Like
Eye - 3/5
Nose - 2/5
blah blah blah

Total = 68/100

but how can you quantify the prettiness of the eyes and noses?
will you give them a discount if it's artificially modified?

i hope someone actually got the joke about the retention rate is an "imaginary" number........... :smile_45:

this hypothesis is significantly different from zero
retention is greater than zero obviously as i  m talking to chef still

you need to redo corp fin and stat

that being said. stat is also my archenemy. i was forced to take it last term as my core too, and barely passed.
i get pwned by regressions

regression is indeed a pain
i fogot all the SST SSR SSE (if there are any) in linear regression after the exams
let alone multivariate regression
statistics is like -  durian - you either like it or hate it

go to a bar, see how many guys approach u. that's a quantity u can count right there.

but one will argue about the quality of those "bees"
obviously if you wear a low cut a lot of guys will approach you but whether you want to hang out with them is another question

if my useless knowledge serves me correctly... complex number is a big deal in electomagnetic stuff, no?

i would think so... those vectors... sounds so electro.... LOL
