Matrix notation?

[rmcelreath]

Hi, Joel.

If there is a way to specify the design matrix style linear model, it's not
really supported. The Stan team has told me that it's not any faster to do
it that way, so I haven't invested any time in it.

But it might not be much work to add it, really. I'll add it to the wish
list.

Hi,

thanks for this package, which seems really great. I also enjoyed the book
a lot.

I wondered if there is a way in map2stan to use matrix notation, as is
possible in stan. Suppose for example I have a matrix of covariates X and
a vector of parameters B, such that y ~ XB, is there anyway to indicate
it in map2stan?

Thanks!

Hi Richard,

take a look at our tutorial. I think the matrix notation does tend to be
faster, and it is certainly easier to generalize, as far as LMMs go:

Also see the example KB07 using Stan in RePsychLing:
