- Sparse Logistic Regression - Spare Logistic Regression (SLR) is a biomarker selection method that suppresses noisy correlated VOCs to zero. Coefficients of the single VOCs are represented versus the penalty of SLR (Lambda).
- Explained variance by age for each VOC - The percentages of explained variance (R2) for age for each VOC are presented. Labels are displayed for VOCs with the 1% highest R2 scores. Based on visual inspection the explained variance of age was below ± 7% for 99% of the VOCs.
- Explained variance by gender for each VOC - The percentages of explained variance (R2) for gender for each VOC are presented. Labels are displayed for VOCs with the 1% highest R2 scores. Based on visual inspection the explained variance of gender was below ± 6% for 99% of the VOCs.
