Hi, list,

I have got a dataset on soil and plant. I would like to fit a "glm" to my data. My response variable is percentage data. That is percent of plant root length colonized by Arbuscular micorrhiza fungi. Because of the nature of my data, I am not quite sure whether gamma or gaussian distribution is suitable for this type of data. If I use gamma distribution, which link function is appropriate?

I appreciate your suggestions very much.

Thanks in advance!
