IPM Library

A quick reference to the IPMs included in epymorph.

No

The ‘no’ IPM: a single compartment with no transitions.

• compartments: P
• transitions: (none)
• requirements: (none)

Pei

The ‘pei’ IPM: an SIRS model driven by humidity.

• compartments: S, I, R
• transitions: S → I, I → R, R → S
• requirements: infection_duration, immunity_duration, humidity

SEIRS

A basic SEIRS model.

• compartments: S, E, I, R
• transitions: S → E, E → I, I → R, R → S
• requirements: beta, sigma, gamma, xi

SIRH

A basic SIRH model.

• compartments: S, I, R, H
• transitions: S → I, I → H, I → R, H → R, R → S
• requirements: beta, gamma, xi, hospitalization_prob, hospitalization_duration

SIRS

A basic SIRS model.

• compartments: S, I, R
• transitions: S → I, I → R, R → S
• requirements: beta, gamma, xi

SparseMod

A model similar to one used in sparsemod.

• compartments: S, E, I_a, I_p, I_s, I_b, I_h, I_c1, I_c2, D, R
• transitions: S → E, E → I_a, E → I_p, I_p → I_s, I_s → I_h, I_s → I_c1, I_s → I_b, I_h → I_c1, I_h → R, I_c1 → D, I_c1 → I_c2, I_a → R, I_b → R, I_c2 → R
• requirements: beta, omega_1, omega_2, delta_1, delta_2, delta_3, delta_4, delta_5, gamma_a, gamma_b, gamma_c, rho_1, rho_2, rho_3, rho_4, rho_5
