edges_correct_het: Adjustment for the Edges Coefficient with Changing Network...

In statnet/EpiModelHIVhet: EpiModel for HIV-1 Infection among Heterosexual Couples in Sub-Saharan Africa

Description

Adjusts the edges coefficients in a dynamic network model to preserve the mean degree.

Usage

edges_correct_het(dat, at)

Arguments

dat	Master data list object of class dat containing networks, individual-level attributes, and summary statistics.
at	Current time step.

Details

In HIV/STI modeling, there is typically an assumption that changes in population size do not affect one's number of partners, specified as the mean degree for network models. A person would not have 10 times the number of partners should he move from a city 10 times as large. This module uses the adjustment of Krivitsky et al. to adjust the edges coefficients on the three network models to account for varying population size in order to preserve that mean degree.

Value

The network model parameters stored in dat$nwparam are updated.
