st: RE: identifying highest number of consecutive variables where answer is consistent across observation

[Joe Canner <jcanner1@jhmi.edu>]

Alison,

When you say "in a row" do you mean "consecutively" or are you referring to rows in the Stata sense (all of the variables for an observation)?

Subject: st: identifying highest number of consecutive variables where answer is consistent across observation

Hi -

I am doing some data cleaning on survey data and am looking to identify observations where there are 15 or more of the same answers in a row (across the variables in current order).  All of the variables are string.  Does anyone have an easy automated way to do this?  I'm thinking that it could be done by generating a variable that provided the maximum number of same responses in a row, but have no idea how to code this.  Variables are q1 - q94, and all string.

Any suggestions on efficiently writing this code would be greatly appreciated.


Best,
Alison
