Hi StatalistBetter still, try -msp- and use Mokken scaling. Jean-Benoit Hardouin's site http://anaqol.free.fr is a great resource here. Essentially, if you are building or evaluating a scale it makes more sense to use item response theory to evaluate the scale as a scale. Mokken scaling is a more 'intelligent' approach than just doing KR20s, as it tries to build a coherent scale from your items, and, when it can no longer add items, it tries to use the remainder to build another scale, until the item pool is exhausted.
just a query on -factor-.
I am trying to construct an index where I have five variables which are binary
I have read somewhere that it is not appropriate to use factor analysis if the
variables are binary. Can anyone confirm, please?
