I have a set of game play event data. One of our goals is to provide a picture of how much time the person has spent playing. This sounds simple but for the fact that events are often dropped and result in vast amounts of time between events.
We are in field trials right now and don't have a huge pool of data to use as reference.
I don't have much experience in statics, though I'm a competent programmer. My question is: What might I do to account for the missing data? How do I ensure that these missing events don't skew my data?
