Re: Median Date

2018-05-02 Thread Jim Freeby
 All,
percentiles only work with numbers, not dates.
If I use the ms function, I can get the number of milliseconds between NOW and 
the import date.  Then we can use that result in calculating the median age of 
the documents using percentiles.
rows=0=true={!tag=piv1 percentiles='50' func}ms(NOW, 
importDate)=true={!stats=piv1 }status
I hope this helps someone else :)  Also, let me know if there's a better way to 
do this.
Cheers,

Jim

 All,
We have a dateImported field in our schema.
I'd like to generate a statistic showing the median dateImported (actually we 
want median age of the documents, based on the dateImported value).
I have other stats that calculate the median value of numbers (like price).
This was achieved with something like:
rows=0=true={!tag=piv1 
percentiles='50'}price=true={!stats=piv1 }status
I have not found a way to calculate the median dateImported.  The mean works, 
but we  need median.
Any help would be appreciated?
Cheers,
