Subject: [Rd] Generic Function for dffits?
Message-ID: <077E31A57DA26E46AB0D493C9966AC730C17E24DD9@UM-MAIL4112.unimaas.nl>

Dear All,

help(influence.measures) shows that there are generic functions for dfbetas(), covratio(), cooks.distance(), hatvalues(), and a few others, but apparently not for dffits(). Wouldn't it be more consistent to have a generic function for this in stats as well?

Best,
