Whether to Include Treatments with 0 means Nonlinear Modeling

Fri, 24 Feb 2017 04:21:39 GMTHi,

I'm trying to compare the effect of temperature on developmental rate using various nonlinear models. The temperatures range 10-35 degrees C.

At the 10 and 35 degree treatments I get no development. I want to know if I should include my 0 development data when fitting my nonlinear models. Looking at the literature it seems to vary whether authors use these 0 data points when constructing the curves or to exclude them and let the models do it. What is the accepted practice?

Dear , I am have tried univariate regression analysis in my project using stata and it gave me the abaove results.The results doesnt make sense to me a ,although the P =0.006, the confidence interval does pass through 1???

Did I do anything wrong?
how to interpret and defend th results this way.
This happen also when I put this variable in multivariate analysis?

thanks in advance
