Dropping observations is missing values

[Jaime Suarez]

Hello community,

I've downloaded a big dataset with data missing across multiple variables in no real pattern. I want to drop all observations with missing data regardless of the variable with missing data (I have over 300 variables and a couple of thousand observations.

Thanks for your help.

If that is what you want to do, then this example should show you a useful direction.

. sysuse auto
(1978 automobile data)

. egen todrop = rowmiss(*)

. tab todrop

     todrop |      Freq.     Percent        Cum.
------------+-----------------------------------
          0 |         69       93.24       93.24
          1 |          5        6.76      100.00
------------+-----------------------------------
      Total |         74      100.00

. drop if todrop>0
(5 observations deleted)
