Use Autonumber() to create Rank for Quartile

[swatitomar]

Hi team ,

i have to create Quartile (1,2,3,4) for that i should rank all the scores in Desc Order and then allocate the top 25% rank 1st Quartile ,Quartile 2 for next will 25% ,Quartile 3 for next will 25% and Quartile 4 for next will 25%.

i'm calculating this on the basis of title , like aggregate the data on title level .

Title: Trainee, Associate, Senior Associate

i tried with Autonumber(Scorces, Title) as Rank order by Scorces Desc;

and Created the range like : min(rank) &'-' & count(Rank)*.25 as Quartile1 ,  same for other also but in case of ties my calculation is not working right..please check autonumber for my result and for correct result check Rank and Quartile .

Need to work in Script.

No ties

All scores	Order the scores	Rank	Quartile
3	42	1	1
4	40	2	1
5	25	3	1
6	21	4	1
7	20	5	2
9	19	6	2
10	17	7	2
13	15	8	2
15	13	9	3
17	10	10	3
19	9	11	3
20	7	12	3
21	6	13	4
25	5	14	4
40	4	15	4
42	3	16	4

In case of ties

All scores	Order the scores	Rank	Quartile	Autonumber Rank	Autonumber Quartile
3	42	1	1	1	1
4	40	2	1	2	1
5	30	3	1	3	1
5	21	4	1	4	1
7	21	4	1	4	1
10	19	6	2	5	2
10	17	7	2	6	2
13	15	8	2	7	2
15	13	9	3	8	2
17	10	10	3	9	3
19	10	10	3	9	3
21	7	12	3	10	3
21	5	13	4	11	3
30	5	13	4	11	3
40	4	15	4	12	3
42	3	16	4	13	4
		17
		18

Thanks in Advance,

As far as I see, the way you want to handle ties, using the same rank for ties and then continuing with the rec number, creating a gap (like missing rank 5, 11, 14 in your sample), Autonumber() is just not the way to go (it will create a consecutive numbering).

Try using a Peek() approach, like

INPUT:

LOAD [All scores],

     [Order the scores],

     Rank,

     Quartile,

     [Autonumber Rank],

     [Autonumber Quartile]

FROM

[https://community.qlik.com/thread/317584]

(html, codepage is 1252, embedded labels, table is @2)

WHERE [All scores];

LOAD [All scores],

  If(Peek('All scores') = [All scores], Peek('NewRank'), Recno()) as NewRank

RESIDENT INPUT

Order by [All scores] desc;

hii.

i have 3-4 fields like,

Tile,Scores, ID ...and i want the answer on the basis of Title, so 1st sort the data on Scores to get the correct rank.

i tired the logic share above but didn't get the correct ans. i want to create the quartile with rank so tried with autonumber() and you are right its not giving me correct ans.

Use Autonumber() to create Rank for Quartile

Ok, if you need to restart the counter for each title, try something like this:

INPUT:

LOAD [All scores],

     [Order the scores],

     Rank,

     Quartile,

     [Autonumber Rank],

     [Autonumber Quartile],

     Ceil(RAND()*2) as Title

FROM

[https://community.qlik.com/thread/317584]

(html, codepage is 1252, embedded labels, table is @2)

WHERE [All scores];

LOAD [All scores],

Autonumber(Recno(),Title) as RecnoTitle,

  If( Previous(Title) <> Title,1,If( Peek('All scores') = [All scores], Peek('NewRank'),Autonumber(Recno(),Title))) as NewRank

RESIDENT INPUT

Order by Title, [All scores] desc; 

[swatitomar]

Hi ,

instead of Recno() i used [All scores] in Autonumber but then also getting the value - after [All scores] are same as i want

1,2,3,4,4,6,7, 8, 9.

byAutonumber([All scores], Title) i created Rank_TL field

LOAD [All scores],

Autonumber(Recno(),Title) as RecnoTitle,

  If( Previous(Title) <> Title,1,If( Peek('All scores') = [All scores], Peek('NewRank'),Autonumber([All scores],

Title))) as NewRank

RESIDENT INPUT

Order by Title, [All scores] desc;

Take care not to use the Autonumber() with same bucket ID (Title) in two different context, counting two different sequences (Recno() vs. All scores.

Besides that, why you've changed to [All scores]?

[swatitomar]

Now I'm using below one only that you have mentioned but not getting the desired result as

if [All scores]=peek([All scores])after that I want next no. like (4,4,6,7)

I have mentioned the desired result above in Rank and quartile field(in case of ties)

and Autonumber rank field, I have created by my logic  "Autonumber(Scorces, Title) as Rank order by Scorces Desc" which is wrong.

LOAD [All scores],

Autonumber(Recno(),Title) as RecnoTitle,

  If( Previous(Title) <> Title,1,If( Peek('All scores') = [All scores], Peek('NewRank'),Autonumber(Recno(),Title))) as NewRank

RESIDENT INPUT

Order by Title, [All scores] desc;

in UI': just take ilst box title and create table box , which contain score, Id , pre1
in case of analyst I m getting 4, 4, 5 ,6 but I want 4, 4, 6, 7 ,8...

in case of Associate , im getting double 1 don't know the reason as score is different and above same  issue is also there

[swuehl]

The line with the Rank calculation is important, because it forces Qlik to calculate the Rec Nr. per title and for every record, even when the else branch of your  pre1 column does not get evaluated.

But as said, the Rank should also be based on Recno(), not the score.

Hence uncomment the Rank and correct the Autonumber() input.

Temp1:
load *,
AutoNumber( recno(),title) as Rank,
Recno() as RecID,
if(Previous(title)<>title,1,if( peek('Total_score')=Total_score,peek('pre1'),AutoNumber( RecNo(),title)))as pre1
Resident Temp  order by title,Total_score desc ; //where not isnull(Total_score)

drop table Temp;
