  • Missing data analysis by interviewdate

    Hi all,

    I am using Stata IC 15 and I have a dataset that refers to data collected over the years (it ranges for 16) years.
    There are some weird missing values patterns in a few variables that we need to understand better. But this patterning is definitely affected by the year the data was collected.
    Is there any way I can have STATA to look at this? I also know that missing values in a specific variable will be related to missing values in another variable.
    I am not leaving any tables or do files as I have no idea on how to do this.
    Hope I can pick someone's brain on this.
    Thanks!!!

    You didn't get a quick answer. You'll increase your chances of a useful answer by following the FAQ on asking questions - provide Stata code in code delimiters, readable Stata output, and sample data using dataex.

    If you look up misstable in the documentation, you may find it addresses your problem.

      Rita:
      I also know that missing values in a specific variable will be related to missing values in another variable.
      You probably refer to the missing at a random (MAR) mechanism of missingness, that is not the only one (see -mi- related entries and references in Stata .pdf manual).
      On missing values at large, see also:

        I did not provide any code, because I have none- I had no idea on how to do it.

        Thanks a lot for the hints. I will have a look!

          If I got it right, you highlighted missing patterns (in#1) but have typed no code (in #4).

          Since you asked

          Is there any way I can have STATA to look at this?
          I recommend to type - help misstable - and check what can be done with - misstable summarize -, -misstable patterns - and other alternatives.
          Best regards,

          Marcos
