I am trying to assign weights to my observations, using the following code:
bf(LDL|weights(weight) ~ 15 + (alpha-15) / (1 + exp ((gamma-Time) / delta)),
alpha ~ 1 + (1|Cat) + (1|Sample) ,
gamma ~ 1 + (1|Cat) + (1|Sample),
delta ~ 1,
nl = TRUE),
where ‘weight’ is a vector of the weights I want to assign to my observations, as instructed here.
However, when I try to run it, I get the following error:
Error: The following variables are missing in ‘data’:
I am not quite sure what the problem is.
Does anyone have any idea?
