llikCauchy {rxode2} | R Documentation |
log likelihood of Cauchy distribution and it's derivatives (from stan)
Description
log likelihood of Cauchy distribution and it's derivatives (from stan)
Usage
llikCauchy(x, location = 0, scale = 1, full = FALSE)
Arguments
x |
Observation |
location , scale |
location and scale parameters. |
full |
Add the data frame showing x, mean, sd as well as the fx and derivatives |
Details
In an rxode2()
model, you can use llikCauchy()
but you have to
use all arguments. You can also get the derivative of location
and scale
with
llikCauchyDlocation()
and llikCauchyDscale()
.
Value
data frame with fx
for the log pdf value of with
dLocation
and dScale
that has the derivatives with respect to the parameters at
the observation time-point

Examples
x <- seq(-3, 3, length.out = 21)
llikCauchy(x, 0, 1)
llikCauchy(x, 3, 1, full=TRUE)
et <- et(-3, 3, length.out=10)
et$location <- 0
et$scale <- 1
model <- function() {
model({
fx <- llikCauchy(time, location, scale)
dLocation <- llikCauchyDlocation(time, location, scale)
dScale <- llikCauchyDscale(time, location, scale)
})
}
rxSolve(model, et)
