Thank you for taking the time to read this!!

I am really stuck with a regression I am doing for my dissertation. Basically it is the categorical variable that is confusing me. The categorical variable 'industry' has three levels - yes, no, or next (indicating whether there is or isnt industry, or whether there is industry in the next state) I also have two other independent variables. My dependent variable is Forest Loss.

When I run the regression in R industrynext 'disappears' (is this something to do with it being a reference var? I really dont know). industryno is significant and industryyes is not.

How would I interpret industryyes and industryno, and what/ where is industrynext??

I hope this has made sense!!

Thank you for any help.
