MARS basis functions. Shown are the basis functions (BF) for the MARS model for dengue hemorrhagic fever.
| Bm | Definition | am | Variable descriptor |
|---|---|---|---|
| BF1 | (IL‐10–1.15) + | 5.83E‐03 | IL‐10 |
| BF3 | (20873 ‐ fibrinogen) + | 5.42E‐05 | Fibrinogen |
| BF5 | (437613 ‐ albumin) + | 1.39E‐06 | Albumin*1 |
| BF6 | (C4A–385932) + | −4.90E‐06 | Complement 4A |
| BF8 | (C4A–256959) + | 3.25E‐06 | Complement 4A |
| BF11 | (469259 ‐ albumin) + | 2.48E‐06 | Albumin*2 |
| BF17 | (122218 ‐ TPM4) + | 5.27E‐06 | TPM4 |
| BF19 | (Immunoglobulin gamma–57130) + | −1.35E‐06 | Immunoglobulin gamma‐chain, V region |
| BF23 | (657432 ‐ albumin) + | −9.97E‐07 | Albumin*3 |
Bm = each individual basis function, am = coefficient of the basis function; (y) += max(0,y); *= variable isoforms likely due to posttranslational modification and/or proteolysis.
