How to measure the performance of proc surveyimpute technique

[Question]

Hi,

I have run imputation on a variable "amt" using proc surveyimpute like this below and I would like to know to measure the accuracy of the technique? Is there any metrics to measure the quality of the imputed data (error measure etc..).

proc surveyimpute data=source method=hotdeck(selection=ABB);
var amt;
class Sex Marital Status Age Region Number_Children 
id unitID;
cells Sex Marital Status Age Region Number_Children ;
output out=source_abb donorid;
run;

Thank you
