A simulation framework for large-scale data generation with applications in the health care domain. The work is a part of the DEMO project http://www.jyu.fi/demo.
Install the released version of the framework from CRAN (not released yet):
install.packages("Sima")Alternatively, install the development version from GitHub:
# install.packages("devtools")
devtools::install_github("santikka/Sima")A simulator consists of events and an initial population. Events come in
two types of R6 class objects, known as manipulation events and
accumulation events. Manipulation events modify the status of initial
population whereas accumulation events introduce new individuals into
the population. The population itself is contained in a data.table and
can be either entirely synthetic or based on real data. To construct a
simulator, first define the events governing the system of interest and
the initial population.
Read vignette("Sima") for more details on how to construct a simulator
for your purposes.
- The package no longer depends on ‘doMPI’, ‘foreach’ and ‘iterators’ packages. Now suggests instead.
- Added explicit support for interventions via the method ‘intervene’.
- All event parameters are now named.
- Now supports derived parameters for events, that change their values automatically if the parameter values change.
- Events can now have their own persistent data.
- Removed
Timeclass as unnecessary.
