Dear all,
I am writing to you because when fitting hmsc to my data I get the
following error:
"Error in rWishart(1, paramX + 1, diag(nparamX)) : inconsistent degrees of freedom and dimension"
I guess it is related to the prior of the sigma matrix of the
multivariate normal of thetas. I have checked the dimensions of my matrices and there does not seem to be any problem.
My data consists of a Ymatrix of community cover data, my X matrix has
three dummy variables (1/0), and my trait matrix has dummy variables as
well.
I ran a model with matrices Y and X, and it worked. However, when I
included the Tr matrix, the model returned the above-mentioned error.
I have tried different strategies like, reducing the number of traits
and including a phylogenetic matrix. However, the error continued.
I would be very thankful for any help,
Sincerely,
