Heey you all,

I'm trying to select the best model by the AIC in the General Mixed Model test. The best model is the model with the lowest AIC, but all my AIC's are negative!

  • So is the biggest negative AIC the lowest value?
  • Or is the smallest negative AIC the lowest value, because it's closer to 0?

For example is AIC -201,928 or AIC -237,847 the lowest value and thus the best model?

Thanks a lot!

Best,

Josephine
