Hello Jamie,
The value that should appear in a missing cell of the data is "NA" without
the quotation marks, if you are using a text-based dataset (eg. a
tab-delimited or comma separated value file). If you are importing a
dataset from another statistical package (Stata, &c), you can leave the
missing value indicator at the default for the that program and Amelia
should be able to properly import the information.
Hope that helps,
matt blackwell.

Dear list members,
I am a complete novice with Amelia. I can't find what the missing data value
should be when I look in the input dataset section of the documentation and
there doesn't seem to be anywhere in the program to specify what value the
missing values take. For example, should the observations given a n/a, . or
-999 value?
Thanks for your time,
Jamie
