Size of effective infectious human population

The trace function for \(\kappa\) follows the ramp.xds standard for time series forcing. The trace function for \(H\) can be modified to follow a trend. Here, \(I = \kappa H\).

Usage

# S3 method for class 'trivial'
F_I(t, y, xds_obj, i)

Arguments

t

current simulation time

y

state vector

xds_obj

an xds model object

i

the host species index

Value
