regression analysis

[mikeczyz]

i have a job interview on monday.

much of the work i will be doing involves running regressions.

i've run a few and interpreted a couple but am basically a noob when it comes to the details of how they work. for example, i have no idea how the math works, i just punch it into excel. and most of what i do know is in the context of specific stock/market returns.

any good websites? most of the sites i've seen are a bit dense.

a question: in the stock/market regressions i've done, the x axis is the independent variable, the y axis the dependent. is x always independent? y always dependent?

thanks.
mike
