Representational mediation model (ReNA-RM)

For each ROI/searchlight, tests whether the ROI RDM mediates the relationship between a predictor RDM (X) and an outcome RDM (Y), optionally including confound RDMs.

Usage

repmed_model(
  dataset,
  design,
  repmed_des,
  key_var,
  distfun = cordist(method = "pearson"),
  ...
)

Arguments

dataset: An mvpa_dataset.
design: An mvpa_design.
repmed_des: Output of repmed_design.
key_var: Column or formula giving item identity in the mvpa_design (e.g. ~ ImageID).
distfun: Distance function to compute the ROI RDM (e.g. cordist(method = "pearson") ).
...: Extra fields stored on the model spec.

Value

A model spec of class "repmed_model".

Examples

if (FALSE) { # \dontrun{
  # Requires repmed_design with X_rdm and Y_rdm
  # model <- repmed_model(dataset, design, repmed_des, key_var=~ImageID)
} # }
