Filtering based on cumulative sum

Tue, 20 Dec 2011 13:53:27 GMT

Hi,

I have a table which is:

Name Value

a 10

b 20

c 30

d 40

Now In a table I want to list the names of people whose cumulative value is not more than 80% of the total value of all people.

To explain further:

The total value for a,b,c,d is 100.

80% of 100 is 80.

So the output should be (Sorted with the highest value coming first)

Name Value

d 40

c 30

Note: It did not display b since if b were put the cumulative value of d,c and b would be 90 which is greater than 80%

Any help would be appreciated.

Regards,

Rajiv

Hi Rajiv

I didn't quite understand why B is comulitive value of D+C rather than A+B, but Anyway:

You can use the following Aggr functions to calculate the comulitive sum of each line:

rangesum(above(sum(Value),0,RowNo()))

Then you divide it by total Sum and you receive the Percent.

After you get the Percent you can just filter by it.

Hope this was helpful.

Hi Ori,

Your rangesum function was useful. However, I was still not able to get the solution.

I have an additional requirement also.

I have the raw data as below:

Name SubName Value

a i 3

a ii 3

a iii 4

b i 6

b ii 6

b iii 8

c i 9

c ii 9

c iii 12

d i 12

d ii 12

d iii 16

Required Output:

i ii iii Tot

d 12 12 16 40

c 9 9 12 30

b 6 6 8 20

Tot 27 27 36 90

Logic:

The name fields are 1st sorted in descending order according to the sum of 'value'

Sum of 'value' is 100. 80% of 100 is 80. So only those 'names' should appear whose 'value' sum up to 80 or just go over 80.

Basically:

sum of d is 40 so 'd' is displayed

sum of d&c is 70 so 'd' and 'c' is displayed

sum of d&c&b is 90 so 'd', 'c' and 'b' is displayed.

Now since the cumulative sum has exceeded 80, no other 'name' gets displayed.

Finally the 'name' value are split 'SubName' wise.

If someone could give an application it would be great.
