Here is my simplified structure:
Log (p)= -4790.529381
Confidence:
min 0.01113009
max 0.105499243

Validation results:
Test:
Alzheimer = 0.741325 (235/317)
Healthy = 0.705128 (110/156)
Diseased = 0.776398 (125/161)
ROC AUC: Healthy: 0.798216
ROC AUC: Alzheimer: 0.798236

Leave One Out:
Alzheimer = 0.697161 (221/317)
Healthy = 0.762821 (119/156)
Diseased= 0.63354 (102/161)
ROC AUC: Healthy: 0.742017
ROC AUC: Alzheimer: 0.742017

4-fold Cross Validation:
Alzheimer = 0.678233 (215/317)
Healthy= 0.775641 (121/156)
Diseased= 0.583851 (94/161)
ROC AUC: Healthy: 0.746835
ROC AUC: Alzheimer: 0.746715

Updated HIV status node to reflect prevalence in Florida and sexual orientation node to reflection national distribution (at this point in time I haven't found any Florida-specific data).
