It might sound like an easy question. What makes me confused is that the independent variable takes any values between 0 and 5 including the numbers such as 1.987. So, I am not sure if I should consider it as an ordinal variable.

  • $\begingroup$ So the outcome is on an interval? Like 0 to 10 and can be any number in that interval? $\endgroup$ Sep 9 at 22:57

    $\begingroup$ Rescale the outcome to be between 0 and 1 and you can use beta regression. $\endgroup$ Sep 9 at 23:23

$\begingroup$

follow the lead of Demetri and rescale the variable to be between 0 and 1. Then you can use beta regression but you also have the fractional logit model in your arsenal, see here.

I hope this helps.
