| Jul 31, 2017 at 11:36 | comment | added | Mike | Just to clarify 100%, I should treat the variables that I measured (temperature, vegetation height, area of scrub etc) as fixed effects? | |
| Jul 31, 2017 at 9:41 | comment | added | Benoit Sanchez | Yes I guess so. I think (in your study) the environment includes random and fixed effects. Fixed effects are what you measure, random effects are what is unknown about the population or the environment :for example individuals in the same population could have unknown genetic similarities that influence $Y$, or there could be something in the environment you're not aware of that influence $Y$ too. | |
| Jul 30, 2017 at 23:17 | comment | added | Mike | Thanks for your answer Benoit. There is slightly more detail in my study that I didn't give in my question - this is a repeated measures study so I think refuge is then a random effect to account for this variation, correct? And do I consider the refuge as my "individual", since I'm counting the reptiles underneath each refuge each time, and my variables relate to each refuge directly? | |
