bdynsys
is a package for panel/longitudinal data that combines methods to model
changes in up to four indicators over time as a function of the indicators itself and up to four predictors using ordinary differential equations (ODEs) with polynomial terms that allow to model complex and nonlinear effects. A Bayesian model selection approach is implemented. The package provides also visualisation tools to plot phase portraits of the dynamic system, showing the complex co-evolution of two indicators over time with the possibility to highlight trajectories for specified entities (e.g. countries, individuals). bdynsys
is also the
name of the main function in the bdynsys
package, that performs the bayesian dynamic
systems modeling.
