1. A computing system to facilitate video playback device viewing data analysis, comprising:
- at least one processor;
a memory comprising instructions executable by the at least one processor to;
receive tune data indicative of content tuned to by a number of video playback devices, the tune data associated with each video playback device including an identification associated with the video playback device and a plurality of tuning events, each tuning event including a time of the tuning event and a corresponding content identifier that was tuned at the tuning event;
identify a first plurality of video playback devices for which power-off event data is available based on the tune data;
analyze the power-off event data to determine one or more times at which the first plurality of video playback devices were powered off;
determine a percentage of the first plurality of video playback devices that were powered off within at least one time interval following a tuning event;
generate a survival curve based upon the percentage; and
assess tune data associated with a particular video playback device by;
selecting a random number corresponding to a probability in the survival curve;
identifying a time from the survival curve corresponding to the probability;
categorizing tune data before the identified time as valid; and
categorizing tune data after the identified time as invalid.

Abstract
A method and system for identifying tune data from set top boxes associated with televisions, video monitors, or other video playback devices that are likely powered off. In some embodiments, survival curves are constructed that predict a length of time before a video playback device is powered off after a tuning event. The survival curves are used to predict the likelihood that a video playback device is powered off. Viewership estimates made from tune data reported from set top boxes can be adjusted to take account of the video playback devices that are predicted to be powered off.
