METHOD Subcommand (RELIABILITY command)
By default, RELIABILITY
uses a computational method that does not require the calculation
of a covariance matrix wherever possible. METHOD
forces RELIABILITY
to calculate the covariance matrix. Only a single specification
applies to METHOD
:
COVARIANCE. Calculate and use the covariance matrix, even if it is not needed.
If METHOD
is not specified, RELIABILITY
computes the covariance matrix for all variables on each VARIABLES
subcommand only if any of the
following is true:
- You specify a model other than
ALPHA
orSPLIT
. - You request
COV
,CORR
,FRIEDMAN
, orHOTELLING
on theSTATISTICS
subcommand. - You request anything other than
TOTAL
on theSUMMARY
subcommand. - You write the matrix to a matrix data file, using
the
MATRIX
subcommand.
