Darshan Hiranandani : How can I implement the Survival Score tool in my workflow?

Question

Hi everyone,

I’m working on a survival analysis project where I need to calculate the restricted mean of the number of months before a contract is canceled. However, I’m encountering some difficulties with the Survival Score tool in Alteryx and am unsure how to proceed.

My knowledge of survival analysis is limited, and I haven’t been able to find clear resources on using the Survival Score tool effectively. Additionally, I’m facing an error message that I don’t fully understand.

I’ve attached a demo workflow for reference. Could someone please help me understand how the Survival Score tool operates and guide me through resolving the error? Any insights or suggestions would be greatly appreciated!

Thanks in advance for your assistance!

Best regards,

Darshan Hiranandani

I haven't used these tools and don't have them installed. You should be able to use the model output of the Survival analysis (trained on your  to score your training dataset) to score your validation dataset. There's not much more to it than that, however if the data is not set up correctly going into the Survival Analysis, then that could cause problems.

Common problems could be (and this is without testing):

* Continuous fields set to string
* Dataset not being split and so returning a perfect model
* Datasets not being compatible and so the model not knowing what to score.

I recommend taking a look through this 4 part series: https://community.alteryx.com/t5/Data-Science/Survival-Analysis-Part-1-Introduction/ba-p/1123558
