What's the best estimation option?

Hi All,

I need to run a regression where the dependent variable is a rating number (simply 1 to 5) and independent variables are 4 ratios which when we add them all they will always be equal to 1.
Attached is a snapshot of the data and I would be grateful if you could help me picking the right estimation method and also if I need to take account for any statistical/econometric issues?

Cheers,
Siroos

The best option is an ordered logit or probit. Just be sure not to include a constant so as to avoid perfect multicollinearity.
