I cannot thank @Charity_K_Wilson and @patrick_mcauliffe enough for being willing to present their work. It's great to see the power of Alteryx in real-life use cases. You two were amazing, thanks!

When we were finishing up the Webinar, a really neat question came in about the Linear Regression output, and how to interpret it. I was having technical difficulties, and couldn't respond at the time. So, now let me answer that question.
The first section of the question asked where I got the accuracy of the equation from. At the bottom of the picture below, the adjusted R squared is circled in a red circle. This metric tells me how accurate the equation is. In this case, I would say that this equation can account for 88% of the variation that is seen in the Insurance Reimbursement rate.
The next question asked about how I understood what things were driving this equation. This is a more complicated question with no easy answer. I've sat thru way to many graduate level courses on statistics. The two rectangles that I've highlighted are the data points that I look at. The green one is called by my prof's the significance. The smaller the number, and the more stars it gets, the better the significance. Another word for significance is also consistency. The more stars it has, the more consistent and reliable it is. The second half of this is in the Orange box. The estimate of the coefficient tells me how much it will move the needle on Insurance Reimbursement. I could read this to say Diagnosis code 4 will decrease the Insurance Reimbursement rate by $110, and it is has a high significance, so I can be confident it will do that every single time.

Hello, I am not sure if it is only me, but I am struggling to hear the audio appropriately in the video provided. it breaks every few seconds.. is there any other way to watch it? I am very interested.
Thanks

Hey @Rawan, so sorry to hear that you're having trouble viewing. The audio is working fine on my end, but I'll send you the MP4 directly to see if that helps. :)
Hello all,
Thanks so much for such a great subject, I am very interested in the workflows and slides used in this one, can you please direct me on how can I access them..
Thanks
Rawan
