Sampling bias in Phoenix
The cut-off of 150 hours introduces sampling bias
Many high-wind fires get cut off, not many low wind
On remaining data, there is no correlation between wind speed and time (r = -0.53)
In fact, data shows that:
- a lot of high wind fires take > 150 hours to contain
- those that don’t are similar to low wind fires
You wouldn’t do this, right? You might if you had automated data analysis.
