What is Data Cleaning? what do the basic steps include? Does anyone have
some experience related to this? I have done some recoding in SAS.
Any input is appreciated.
thanks

A incomplete list of things to do:
switch data format (e.g. numeric to categorica, or from wide to long)
deal with missing value
deal with truncated data
deal with multicollinearity
explore relationship
etc
