Hi, I am working with BHPS dataset. I have appended Waves 9 & 10 and have declared it as panel. Using the command xtdes, I could see that not all info are available for all individuals in both waves and would want to drop individuals with info in either wave only. My unique identifier of each individual is pid. As you can see, some individuals have info in both waves (var wave) and some do not. How do I drop those individuals with data not available in both waves?
