Identifying multiple influential observations in linear regression

Imon, A. H. M. Rahmatullah - In: Journal of Applied Statistics 32 (2005) 9, pp. 929-946

The identification of influential observations has drawn a great deal of attention in regression diagnostics. Most of these identification techniques are based on single case deletion and among them DFFITS has become very popular with the statisticians. But this technique along with all other...
