Outlier Detection Logic at Product/Store/Date level

EDNA,

Good day. I’m attempting to create outlier detection logic similar to what is outlined within the Detecting and Showcasing outliers lecture, however, I’m having trouble applying the concepts within the lecture to my use-case.

In this situation, I’m trying to group high, low, and non-outliers based at the product/store/date level based on (1) the percentage difference between a forecast for a single product/store/date and the average of sales for the that product/store across multiple dates and (2) the forecast value itself. I’d then like to plot the data points in a scatterplot using the 3 outlier groupings.

I’ve attached sample data and .pbix. The sample data file contains an “Objective” tab which describes provides an example and the expected results.

Any assistance or guidance would be much appreciated. Thanks!

@_mk7,

Wow, impeccable timing on this question. I have a YouTube video coming out on Enterprise DNA TV this Friday at 9am ET on almost this exact scenario. Here’s the initial post and solution that prompted me to make the video:

This is a simpler case than yours, but the video deals with more complex, multidimensional scenarios that mirror your question. Please take a look at the above post, and if that doesn’t provide a sufficient solution for you and you need an answer before Friday am, let me know. Thanks!

@EnterpriseDNA @BrianJ The video was helpful regarding how to set up multiple dynamic outlier conditions.

Would it be possible to provide some guidance on the DAX required to calculate the percentage difference between a forecast for a single product/store/date and the average of sales for the that product/store across multiple dates (as referenced in the sample data “Objective” tab)?

Thanks!
