An example, the time someone left home and the time someone called 9-1-1 and put these points in to predict ideally the time of incident on an excel format. I can put in a time in column a and column b but all it does is give me the half way point between the two. example column a says 12:00 and column b says 1:00 and the result would be 12:30. If I can get some thing more predictive using this approach, that is ideally what I'm looking for.
I used some of the standard functions in Excel to predict time based series.
We were looking at predicting data points for 1mis, 3mis and 6mis (mis = Months In Service).
We found that the forecast() function with some "fiddle" factors - sorry finely tuned polynomial assumptions - gave a reasonable prediction for our needs. We fed it steps of historical data to see the performance until it was suitable for what we needed.
