kaisers_index
computes scores designed to assess the quality of a factor
analysis solution. It measures the tendency towards unifactoriality for both
a given row and the entire matrix as a whole. Kaiser proposed the evaluations
of the score shown below:
In the .90s: Marvelous
In the .80s: Meritorious
In the .70s: Middling
In the .60s: Mediocre
In the .50s: Miserable
< .50: Unacceptable
Use as basis for selecting original or rotated loadings/scores in
factor_analysis
.
