Arrival target setting using HDF
Description
Employs dm.hdf
over time to estimate the arrival of known specifications.
Usage
1 2  target.arrival.hdf(xdata, ydata, date, t, rts="crs",
wd=NULL, sg="ssm", ftype="d", cv="convex")

Arguments
xdata 
Input(s) vector (n by m) 
ydata 
Output(s) vector (n by s) 
date 
Production date (n by 1) 
t 
A vantage point from which the RoC is captured 
rts 
Returns to scale assumption 
wd 
Weak disposability vector indicating (an) undesirable output(s) (1 by s) 
sg 
Employs secondstage optimization 
ftype 
Frontier type 
cv 
Convexity assumption
