FoI combines parameters related to HIV transmission via needle sharing, heterosexual sex and homosexual sex
FoI( y, no, uoC, ns, usC, eO, eS, sigmaFM, sigmaMF, sigmaM, tau, eff.prep, d, s, eff.oat, cov.ssp, eff.ssp = eff.ssp, s.multi, bal = F )

|---|---|
| no | number of opposite sexual partners for each compartment (n.gp*19 matrix) |
| uoC | condom use adjustment term for opposite sex (n.gp*19 matrix) |
| ns | number of same sexual partners for each compartment (18*19 matrix) |
| usC | condom use adjustment term for same sex (18*19 matrix) |
| eO | assortative coefficient for heterosexual mixing between ethnic groups (vector of 3 for white, black, hispanic) |
| eS | assortative coefficient for homosexual mixing between ethnic groups (vector of 3 for white, black, hispanic) |
