Regression help

Helpneeded86

I have to do a regression as part of my thesis but I am pretty much close to new with them. Can anyone point a good place to start?

How basic or advanced will the regression be?

My dependent variable is share price movement for a 3 year period taken at year end at each year.

My independent variable is female directors as a % of the board.

Stata would be the most common econometrics software package, your university should provide you access free of charge.

I have done the regression. I would just like confirmation that the results pretty much mean my data does not show any real relation.

Your R^2 is pretty low which would indicate a small level of relation. But like anything in statistics it really depends on where you want to set the cut off point.

OP, do you have any other independent variables?

I updated it with board size. These are the results I got.

Do you have any other independent variables which might also explain a company's share price movement? As in, what you want to show is that the %of female directors is significant, after taking other relevant factors into account. So for example, share prices are plausibly affected whether there's an ongoing recession or not. So you might want to control for that. There are likely many papers which try to use regressions to explain share price movements using a variety of factors, so you could try searching google scholar for some ideas as to what variables to include.

Also, re. the dependent variable. You said it's the share price movement. As in, are you looking to see whether more women = less volatile share price? Or a more volatile share price? (i.e. are you looking at the variance in the share price). Or are you looking to see whether more women means share price growth/or contraction, (i.e. the growth rate of the share price over the period).

Also, make sure that you've got a solid theory as to why the number of women on a company's board might affect share price at all. I presume you've thought about that, but I figured it was worth reiterating; a nice regression result doesn't prove anything in and of itself.

I am looking for a relation between share price and the number of female directors. There has been a lot of studies and most used ROA and ROE. My model is going to be a lot more simplistic.

I decided to minimise the regression end of this research as I am simply not very good at it. I explored other avenues in the area in order to make the project look good. I understand the regression is below par compared to what it could be but I gues it is best to work with your strengths.
