Case deletion diagnostics tool in PsN

[SaraSALHI2]

Hi,
I am currently working on the case deletion diagnostics (CDD) tool in PsN and I was hoping you could kindly provide some clarification on its outputs. I have the following questions:

• What is the exclusion criterion for individuals mentioned in the first plot of the PDF entitled "covariance ratio vs cook scores"?
• How are the cook scores and covratio cutoffs derived?
• What is the rule applied to identify individuals as influential individuals?

Thank you very much for your time and assistance.
Best regards,

1. The plot is really something we used to compare covariance ratio and cook scores. Not really intended for end users.
2. The cutoffs are more or less arbitrary. For the dOFV metric we use 3.84 as if one degree of freedom was removed.
3. For dOFV see 2. If using cook score there is another cutoff

Could you please advise the cook score cutoff and how was it chosen

Thank you
