Regarding algorithm summary of R algorithm

[Former Member]

Hi everyone

I am new to this SAP Predictive Analysis. I have this doubt regarding the summary that gets created when I run algorithms specially R algorithms in SAP expert analytic.

Like in the below attached screenshot. The summary details it shows, it couldn't interpret completely.

Can you tell me the approach how to go about these algorithms in detail.

What does those indicators imply in the summary screen?

Hi,

There is some information already here: http://help.sap.com/businessobject/product_guides/pa21/en/pa21_expert_user_en.pdf

Look pages 164-165

I will search if I see more info related to the summary screen.

Best

hey Paul,

Thanks a lot.

Another doubt which I am having is among all those parameters exactly which one defines the fitness %age or error margin of that model?

I understood the summary part, thanks guys

The Value 0.3 is the alpha value,

and the coefficient a=48.66011 is the level.

Thanks Antoine, waiting to hear from Paul Pallath or Jayanta Roy.

One more doubt is in the above snapshot, which factor exactly determines the fitness % of the model?

Thanks Antoine CHABERT for such prompt response. I did go through the documentation, but its very generic. The snapshot which I attached has things like fitted, call, SSE, coefficients etc. which are more technical.

Like this if I try using any other R package, like that another complicated summary gets generated.

What should be my approach here to get accurate result out of that algorithm?

Kindly help me out.

Hi Ranajay,

Maybe or can take a look at this and better help you, as I am not an R expert...

Thanks & regards
