e0.median.set {bayesLife}R Documentation

Editing the Projection Medians


These functions are to be used by expert analysts. They allow to change the projection medians either to specific values or shift the medians by a given constant.


e0.median.set(sim.dir, country, values, years = NULL, joint.male = FALSE)

e0.median.shift(sim.dir, country, reset = FALSE, shift = 0, 
    from = NULL, to = NULL, joint.male = FALSE)
e0.median.adjust.jmale(sim.dir, countries, factors = c(1.2, 1.1))

e0.median.reset(sim.dir, countries, joint.male = FALSE)



Directory containing the prediction object.


Name or numerical code of a country.


Vector of country names or codes.


Array of the new median values.


Numeric vector giving years which values correspond to. Ideally it should be of the same length as values. If it is NULL, values are set starting from the first prediction period. If values correspond to consecutive years, only the first year might be given here. A year t represents a prediction period [t_i, t_{i+1}] if t_i < t ≤q t_{i+1}.


Logical. If TRUE, the function is applied to a male prediction that was generated using the joint female-male model implemented in the function e0.jmale.predict.


Logical. If TRUE medians in a range of from and to are reset to their original values.


Constant by which the medians should be offset. It is not used if reset is TRUE.


Year from which the offset/reset should start. By default, it starts at the first prediction period.


Year until which the offset/reset should be done. By default, it is set to the last prediction period.


It should be a vector where each element corresponds to one time period. The adjustment of male medians is done as e0m(t) = e0f(t) - gap(t)*factor(t).


The function e0.median.set can be used to set the medians of the given country to specific values. Function e0.median.shift can be used to offset the medians by a specific constant, or to reset the medians to their original BHM values. Function e0.median.adjust.jmale adjusts male medians using factors that can expand or shrink the female-male gap. Function e0.median.reset resets medians of the given countries to the original values.

In all cases, if a median is modified, the corresponding offset is stored in the prediction object (element median.shift). All three functions write the updated prediction object back to disk. All functions in the package that use trajectories and trajectory statistics use the median.shift values to offset the results correspondingly.


All three functions return an updated object of class bayesLife.prediction.
