Hi all, I would like to have a follow-up question on the topic asked earlier and locked. Can anyone help with details on the mothod suggested here? I follow this instruction, get Sp, Se, Pos predictive, Neg predictive but do not see each level of continuous variable (for example absence day). Thank you! https://communities.sas.com/t5/Statistical-Procedures/determine-significant-cut-off-points/m-p/79628 ... View more
