How to write Outliers and Influential point obs in a dataset in prog reg?

I would like the observation number of outliers and influential points of Studentized residuals and Cook's D in an output dataset. The purpose is I may wanna examine further and decide to keep or delete them from my sample

proc reg data=prop_dummy1_dropped_insig outest=est;
model price= BATHRM NUM_UNITS
ROOMS
BEDRM
YR_RMDL;

outest=est; doesn't seem to have it 😞

Thank you for your help

OUTEST only contains slopes and related quantities, and does not contain information for each record (observation).

You want the OUTPUT data set, which contains information for each record (observation)

@PaigeMiller Sir, You are the man!!!. My apologies for bothering your time for something I should have found out. But kindly bear with me and forgive me. My research skills nor stat skills are not up to mark.

And while I am on the course to learn anova, linear, logistic and principal components as well as I can, I might throw open a few questions.

Cheers! and Thanks you!!!
