How do we calculate beta coefficient (standardized R) for results of a mixed regression model with negative binomial distribution please?
What does a standardized regression coefficient mean here and how would you standardize it anyway? D Booth
Thanks David Eugene Booth I'm in the field and will get back to u soon - Ran
Standardized coefficients are with uniformed measurement units and are used for comparison of variable strength. I have trouble finding suitable r packages calculating beta for a glme.nb model.
For the PDMS material, it's linear thermal expansion coefficient is about 3.2*10-4/℃. The polyimide has a smaller linear thermal expansion coefficient like 2*10-5/℃, but it cannot be stretch. It...
