Validity report for construct models

Usage

validity_report(loadings, construct_scores = NULL, items_by_construct = NULL)

Arguments

loadings: A data.frame with columns construct, item, and loading, or a named list of loading vectors by construct.
construct_scores: Optional data.frame of construct scores for Fornell-Larcker and inter-construct correlations.
items_by_construct: Optional named list, one element per construct, each a data.frame of that construct's item-level responses. When supplied, htmt is the Henseler heterotrait-monotrait ratio: the mean absolute heterotrait-heteromethod correlation over the geometric mean of the two constructs' mean absolute monotrait-heteromethod correlations. Constructs with a single item have no monotrait correlations, so their HTMT entries are NA. Without this argument, htmt falls back to the absolute inter-construct correlation matrix from construct_scores (the pre-0.3.4 behaviour). The htmt_method element records which was computed.

Value

An object of class sframe_validity_report.

Examples

loadings <- list(
  sq  = c(sq_1 = 0.80, sq_2 = 0.75, sq_3 = 0.78),
  sat = c(sat_1 = 0.85, sat_2 = 0.82)
)
vr <- validity_report(loadings)
