This is not a code error. Most likely, you don't have enough data to estimate desired parameters given the complexity of your model. Alternatively, there is not enough variability in your data for the algorithms to do their job. Solutions would be: - Simplify or change your model. - Get more data. - Introduce more variability.

Great! And congratulations on your post-doc.

I suggest you move this topic over to the statistics forums.

These are on the logit scale. You need to un-transform the results.

Thank you!

I think both are equality. If both one and two are normal distribution, then dif=one-two must be normal distribution. because dif is linear combination of normal distribution.

Thanks all.

Thanks so much. You actually hit the nail on the head. The model I originally posted is the Briere-1 Model: aT(T-Tmin)(Tmax-Tmin)**(1/2) He also proposed a more generalized model Briere-2: aT(T-Tmin)(Tmax-Tmin)**(1/m), where m is a 4th parameter to estimate. Using your code and adding m I predicted m ~ 2.75. By adding this term the RSS went from 0.500 to 0.4096. So yes by modifying the exponent you tend to get a better fit of the data.
