Reasons behind break in Rank Ordering?

[dkanand86]

Hi All,

I have developed a booking propensity model on my active customer base.

I observe a break in Rank Ordering on Out of Time data in 5/6 decile.

Please, can you help me understand what could be the potential reasons for this break?

Please advise,

Thanks!!

Please provide:

Example Data in the form of a data step so can test the code. The example data should demonstrate the issue involved.

Code used on the data

Actual results

Description of why you think the actual results have a "break".

This type of question is both data and code options chosen dependent and possibly even format dependent depending on how you are deciding there is a break if you are looking at numbers and not showing enough digits/decimals.

Or possible even understanding what a decile is.

If I have 10 values and they are 1 2 3 4 5 60 61 62 63 64 then there is a "break" between the 5th and 6th decile because the values have a large difference. Or if the data is 1 1 1 1 1 4 5  6 7 9, the first through 5th deciles are all 1. So multiple repeated values may be impacting your consideration.

Deciles are order statistics and you are dividing the provided data into 10 groups based on the sort order of the values.
