(1) Exist a package to do something like
missing value analysis for a specific data.frame?
(2) Know anybody ,how it is possible check the data
for plausibility from one respondend. So i would like
identify critical fake respondents and clean them from further analysis..
In Conjoint-Mesaurement data, a plausability test are done
with correlation - is something similar possible in a standard survey !?
..until now i didn't get a good idea which statistic-method could support me for
this?
many thanks for any suggestions
