fcenLRinv {robCompositions} | R Documentation |
Inverse of fcenLR transformations (functional)
Description
Inverse of fcenLR transformations
Usage
fcenLRinv(z, z_step, fcenLR, k = 1)
Arguments
z |
grid of points defining the abscissa |
z_step |
step of the grid of the abscissa |
fcenLR |
grid evaluation of (i) fcenLR[lambda] transformed lambda-density, (ii) fcenLR[u] transformed P-density, (iii) fcenLR[P] transformed P-density |
k |
value of the integral of density; if k=1 it returns a unit-integral representation of density |
Details
By default, it returns a unit-integral representation of density.
Value
out
... grid evaluation of (i) lambda-density in B2(lambda),
(ii) P-density in unweighted B2(lambda), (iii) P-density in B2(P)

Examples
# Example (normal density)
t = seq(-4.7,4.7, length = 1000)
t_step = diff(t[1:2])
mean = 0; sd = 1.5
f = dnorm(t, mean, sd)
f1 = f/trapzc(t_step,f)
f.fcenLR = fcenLR(t,t_step,f)
f.fcenLRinv = fcenLRinv(t.fine,t_step,f.fcenLR)
plot(t,f.fcenLR, type="l",las=1, ylab="fcenLR(density)",
cex.lab=1.2,cex.axis=1.2, col="darkblue",lwd=2)
