Index Target Effort-Based
Description
An index target MP where the Effort is modified according to current index levels (mean index over last 5 years) relative to a target level.
Usage
ITe5(x, Data, reps = 100, plot = FALSE, yrsmth = 5, mc = 0.05)
ITe10(x, Data, reps = 100, plot = FALSE, yrsmth = 5, mc = 0.1)
Arguments
x |
A position in the data object |
Data |
A data object |
reps |
The number of stochastic samples of the MP recommendation(s) |
plot |
Logical. Show the plot? |
yrsmth |
The number of historical years over which to average the index |
mc |
The maximum fractional change in the effort among years. |
Details
The TAE is calculated as:
\textrm{TAE}_y = \textrm{TAE}_{y-1} \delta
where \delta
is \frac{I} {I_{\textrm{ref}}}
averaged over last
yrsmth
years. I_{\textrm{ref}}
is the index target (Data@Iref
).
The maximum fractional change in TAE is specified in mc
.
Value
An object of class Rec-class
with the TAE slot(s) populated
Functions
