Dfbeta Stata Command. Which are your outcome and predictor variables. We use the dfbeta command to generate DFbeta values for each variable and observation.
The Dfbeta Command Linear Regression Post Estimation from www.techtips.surveydesign.com.au
Where Rstudent is the studentized residual. For multiple-record data by default only one value per subject is calculated and it is placed on the last record for the subject. Simply run a regression then type dfbeta indep var.
Type predictif esampleif wanted only for the estimation sample.
DFBETA shows how much a coefficient would change if that case were dropped from the data. In particular we will see that the dfbeta statistics can be easily computed for any command that accepts the jackknife prefix. The DFbeta value shows the degree to which the coefficient will change when that observation is omitted. May 08 2014 To compute the dfbeta value for the coefficient for difficulty we type.
