In summary, the conversation discusses the need for a second opinion on a solution for determining if a newly arrived file has a low number of records compared to others. The proposed solution involves computing the mean A for total records from 6 months ago, sorting the data and computing the mean B for the lowest 30 values, and using this to create a minimum index point. The total record for the new file will be divided by mean A and compared to the minimum index point to determine if it is a low-volume file. However, the flaw in this method is that the definition of "low-volume" is not clear. Other potential issues to consider are the detection of outliers and order statistics.

I would like to hear a second opinion about this solution that was presented to us.

As a background, we have a system that will compute for the total number of records for a given a file. The arrival time for each file is set for 5 minutes. For monitoring purposes, the problem now is how to determine if the computed record for the newly arrived file is a low-volume file, meaning the number of record is very low compared to the other files.

The solution that was presented to us was this. First, the mean A for the total number of records from 6 months ago will be computed. Then, the data will be sorted from lowest to highest, get the top 30 lowest data and compute for the mean B. The mean B will then be divided by mean A and the resulting value will be called a minimum index point.

Afterwards, the total record for the newly arrived file will be divided by mean A. The value for this computation will then be compared against the minimum index point. If the value is lower than the minimum index point, an alarm will be generated informing the user that the current file is a low volume file.

Is there any flaw with this method? Or is there a more efficient solution for this particular problem?

The only flaw in it is that you have not defined what 'low-volume' means. As far as I can tell, you seem to have declared something to be low-volume if it fails this test. That may or may not be what you want - we don't know.
 

What is a second opinion for an index problem?

A second opinion for an index problem is when a person seeks the advice or evaluation of another expert or professional in order to confirm or challenge the initial diagnosis or solution proposed by the first expert. This can be done for various reasons such as wanting to explore alternative options, ensuring accuracy, or gaining peace of mind.

Why would someone need a second opinion for an index problem?

There are many reasons why someone might seek a second opinion for an index problem. Some common reasons include wanting to confirm the accuracy of the initial diagnosis, exploring alternative solutions or treatment options, or simply wanting to gain peace of mind before making a decision.

How do I know if I need a second opinion for an index problem?

If you are unsure or have any doubts about the initial diagnosis or proposed solution for your index problem, it is always a good idea to seek a second opinion. It is also recommended to seek a second opinion if the initial diagnosis or solution seems complex or risky, or if you are not satisfied with the communication or explanation from the first expert.

Who can provide a second opinion for an index problem?

A second opinion can be provided by any qualified expert or professional in the field of the specific index problem. This can include specialists, experienced practitioners, or even other scientists or researchers who have knowledge and expertise in the area. It is important to choose someone who is reputable and has a good track record in their field.

How do I go about getting a second opinion for an index problem?

The first step is to research and identify potential experts or professionals who can provide a second opinion for your specific index problem. You can ask for recommendations from your primary care physician or do your own research. Once you have identified a potential expert, you can schedule an appointment or consultation to discuss your concerns and seek their opinion. It is important to be open and honest about your concerns and to provide all necessary information for an accurate evaluation.
