Fixing parameter ERROR in brms

Interfaces brms
1

Dear all,

I’m performing a multilevel analysis using brms. But, return an ERROR when I constructing the model using bf function:

n1 <- bf(e_50 ~ e_0 + (1 + e_50|Season + SurveyID), data = data) +  zero_inflated_poisson('log')

Error: Expecting a single value when fixing parameter ‘data.SurveyID’.

Data example:

SurveyID Season e_50 e_0
1 Winter 2006 4 5
2 Winter 2006 0 1
3 Spring 2006 2 0
4 Spring 2006 0 2
5 Spring 2006 0 6
  • Operating System: Windows 10
  • brms Version: 2.13.0
2

data is not an argument of bf() but of brm()
