I am trying to run a GLMM with a quasibinomial family (my data is 0 inflated and I have a negative min x value), but am receiving this error message as quasi families cannot be used in glmer:

Error in lme4::glFormula(formula = slope_prop ~ temp * gly * day + (1 |  : 
  "quasi" families cannot be used in glmer

Is there any way of running a glmm which will use quasi families? Or am I doing the wrong thing by trying to use a quasibonomial family in the first place?

Many thanks for any advice!
