"...but in my SPSS Statistics 22 I can't find the Analyze>Mixed Models option in this version..."
I suspect you don't have the Advanced Statistics Module installed.  That is where you would find MIXED.

Dear all,
I'm totally new to statistics and doing research on whether profitability influences companies' graphical use and for that I have gathered data for 23 companies over 10 years. For all company years I noted whether they were profitable or not and the amount of graphs they included in their annual report. Now I want to know whether they included more/less graphs when they are profitable compared to when they make a loss. I think I need to run a fixed effects regression where the dependent variable Y is the number of graphs and the formula will be as follows:
 Yit = α + β*D + t + λ
α = constant
β = effect of profit
D = Dummy-variable for profit
t = time fixed effect
λ = industry fixed effect
Does that seem plausible given what I want to research?

I've found tutorials with (I assume other versions of) SPSS executing a regression like that but in my SPSS Statistics 22 I can't find the Analyze>Mixed Models option in this version. Is there another way to do this? Or is it nog possible in this SPSS version?
Furthermore, can anybody explain to me how I start? This might sound silly, but I don't have a clue as to in what format I should put my data (e.g. wide/long, a new variable column for every year or not, etc).

Thanks in advance for taking the time to help me out, much appreciated!
