Description

Function memstability perform an analisys of stability of estimators

Usage

1
memstability(i.data, ...)

Arguments

i.data

Data frame of input data.

...

other parameters passed to memmodel.

Details

Shows the stability of the main indicators according the number of seasons used to calculate them. That allows to decide the minimum and maximum number of seasons to be included in the model for this specific country and parameter.

These indicators are calculated for the next upcoming season, so for all the iterations are used the last number of seasons determined by the x-axis, so that 2 means 'last two seasons', 10 means 'last ten seasons' and so on.

The stability.seasons output shows data used to calculate each particular point in the graph.

Value

memstability returns a list. A list containing at least the following components:
