In doing data manipulations, an important step is to make sure the source data is valid. I’m trying to clean house a little so in a way, I’m hoping to have more garbage out than in. It reminds me of a line from Seinfeld when Heather and I went to see him in a live performance. He said something to the effect that everything we buy is trash. We buy it and are happy about it and love it, but eventually it will become trash and we’ll throw it away. Just think of all that old computer gear that might be in your closet that is not worth anything, even for a donation, that you will eventually just throw away.
So, the next time you buy something, make sure that your source data is valid and hopefully your “garbage out” will not be too close to your “garbage in”.
