Calculating average of top N % of distribution

Hi all,

I am trying to calculate the average of a subset of a distribution. In the picture below I show two examples.

QlikView distribution avg.png

In the left chart, the average of the full distribution is calculated, with the following formula:


However, what I'm trying to accomplish is calculating the average for the top 70% mass of the distribution. I am fairly certain that this can be achieved with a combination of the aggr, rank, rangesum, and similar functions, but I haven't gotten it to work.

Does anyone have any ideas?

Any help is greatly appreciated!

Best regards,

Re: Calculating average of top N % of distribution

These are the kind of solutions that I teach at the Masters Summit for Qlik, within my lecture about Set Analysis and AGGR(). If you posted a more specific example, I could give you a more specific solution. In the absence of a specific formula, here is a generic one:

avg = avg( AGGR( sum( {<Dimension= {"=(calculation of the bucket)>=7 "} >}  Measure) , Dimension))

In a nutshell, you need to average out the results only for those Dimension values that were associated with the top three buckets.

Notice that by Dimension here I mean the actual dimension that's participating in the histogram, not the buckets 1-9. Again, it would be easier to explain on a more specific example.

Re: Calculating average of top N % of distribution

Dear Oleg,

Thanks for your reply. I will try to flesh out my problem a little, as well as provide a small sample application.

In my example, the total sum of my measure totals to 155. The measure is distributed over a dimension with values 1 to 9. The total distribution average, given the distribution, in this case comes out to 5.4 (see application). I want to know the average of the top 70% of my measure. In this case, I want to know the average of the 155*0.7=108.5 measure values which occur in the upper end of my distribution.

Thanks so much in advance!

Best regards,
