Prepare country parameters for model

Source: R/class_country.R, R/class_infection.R, R/class_vaccination.R, and 1 more
prepare_parameters.Rd

Generic for the prepare_parameters methods associated with daedalus classes.

Usage

# S3 method for class 'daedalus_country'
prepare_parameters(x, ...)

# S3 method for class 'daedalus_infection'
prepare_parameters(x, ...)

# S3 method for class 'daedalus_vaccination'
prepare_parameters(x, ...)

prepare_parameters(x, ...)

Arguments

x

An S3 object with an appropriate method.

...

Not used; included for compatibility with methods.

Value

A list of parameters suitable for the DAEDALUS model. prepare_parameters.daedalus_country() returns the country parameters, while prepare_parameters.daedalus_infection() returns infection parameters.

Details

Country parameters

Country contact data is processed as follows:

  • contact_matrix: scaled by its leading eigenvalue, and with each column j scaled by the j-th element of the country demography vector (i.e., scaling contacts from each age group by the size of that group).

The returned parameter list consists of:

  • demography: the demography vector;

  • contact_matrix: the contact matrix;

  • contacts_workplace: the contacts in workplaces scaled by the number of workers in each sector;

  • contacts_consumer_worker: contacts in workplaces distributed in proportion to the demography distribution, and scaled by the largest singular value (similar to eigenvalue for non-square matrices).

Infection parameters

Infection parameters are returned from <daedalus_infection> objects without modification and only the name removed.
