A summary of the MUDFOLD scale that has been calculated with the mudfold
function.
The output of the summary.mdf()
is a list with two main components. The first component of the list is a data.frame
with scale statistics and the second component is a list with item statistics. If diagnostics=TRUE
another component with diagnostic matrices is also included in the output. When the bootstrap scale estimate does not agree with the obtained MUDFOLD estimate a summary of the bootstrap scale will be given in the output.
