Hello,
Curreny I am writing my master thesis about the impact of financial variables on soccer performance. My dataset consists of 23 clubs which played in the highest Dutch soccer division between 2004-2005 and 2013-2014 (ten seasons). Eighteen clubs participate in one season. In a perfect world the dataset would consist of 180 observations per variable, this dataset consist of 170 observations. In the ten season period investigated there are twelve clubs with an ongoing participation in the division, my data is complete for these twelve clubs.
My financial variables are: net revenue, net profit, salary expenditure and the transfer results. My sport performance variables are, win percentage, log league points and log standings.
My question is what data set is the most appropriate to analyze the data. Unbalance or balanced panel data?
With unbalanced data, it suffers from attrition due to relegation of football clubs. With balanced data (12 clubs) my data suffers from sample selection bias. I use Stata 12.
Kind regards,
Jordi van Dijk
