Changes in version 0.13.4 (2024-10-07)                 

  - The source code is now hosted in a public Git repository at
    https://codeberg.org/EE-hub/hhh4contacts.

                 Changes in version 0.13.3 (2023-11-06)                 

  - The package now formally depends on sp (S4 class used by map data),
    not only implicitly via surveillance.

                 Changes in version 0.13.2 (2023-10-23)                 

  - Minor documentation improvements and updates.

                 Changes in version 0.13.1 (2020-03-20)                 

  - Maintenance for new S3 method lookup in R 4.0.0.
    NextMethod("confint") in confint.fitC() wouldn't find a method if
    confint.fitC() was called directly from summary.fitC().

                 Changes in version 0.13.0 (2017-06-30)                 

This is the first version published on CRAN. It requires surveillance
>= 1.14.0. The main change is in the documentation, which became more
comprehensive, especially for the included datasets.

Other changes include:

  - Changed the default agegroups parameter in noroBE() (and grouping
    parameter in contactmatrix()) such that it corresponds to the six
    age groups used by Meyer and Held (2017).

  - The aggregateC() function is now exported.

                       Changes in version 0.12.6                        

This version has been used for the publication

Held L, Meyer S and Bracher J (2017). "Probabilistic forecasting in
infectious disease epidemiology: The 13th Armitage lecture." Statistics
in Medicine, doi: 10.1002/sim.7363.

New features

  - An additional year of norovirus surveillance counts has been added,
    such that noroBE() can now extract data from the time range 2011-w01
    to 2016-w30.

  - noroBE(by = "none") extracts the overall univariate time series.

  - update() method for "fitC" objects, which enables modification of
    the "hhh4" model with automatic refitting of the power parameter of
    the contact matrix.

  - plotHHH4_season_groups() gained an option to disable confidence
    intervals.

Bug fixes

  - A typical drop=FALSE bug prevented aggregateC() from aggregating a
    contact matrix to only two groups.

                       Changes in version 0.12.1                        

This is the original version published as supplementary data of

Meyer S and Held L (2017). "Incorporating social contact data in
spatio-temporal models for infectious disease spread." Biostatistics,
18(2), pp. 338-351, doi: 10.1093/biostatistics/kxw051.
