mobj_refit_lm R Documentation
Helper function to re-calculate the l3 design matrix for a model based on available data
Description
Helper function to re-calculate the l3 design matrix for a model based on available data
Usage
mobj_refit_lm(mobj, new_data)
Arguments
mobj
a hi_model_spec object containing the L3 GLM model to run
data
The run-level data frame containing data for all ids and sessions. This will be split into individual chunks
Details
The function adds the $by_subject field, which contains the design matrices and contrasts
for each subject and session in data based on the available data for that session. For example, if
a subject is missing a few runs (or these are dropped from analysis), then some contrasts may change or drop out
of the model.
The $by_subject field is a keyed data.table object containing list elements for the cope_list (mapping cope numbers
to contrast names), the contrasts, and the design matrix for each session.
Value
a modified copy of mobj where the $by_subject field has been added
