llikNorm {rxode2}

Log likelihood for normal distribution

Description

Log likelihood for normal distribution

Usage

llikNorm(x, mean = 0, sd = 1, full = FALSE)

Arguments

x

Observation

mean

Mean for the likelihood

sd

Standard deviation for the likelihood

full

Add the data frame showing x, mean, sd as well as the fx and derivatives

Details

In an rxode2() model, you can use llikNorm() but you have to use all arguments. You can also get the derivatives with llikNormDmean() and llikNormDsd()

Value

data frame with fx for the pdf value of with dMean and dSd that has the derivatives with respect to the parameters at the observation time-point

Examples

llikNorm(0)

llikNorm(seq(-2,2,length.out=10), full=TRUE)

# With rxode2 you can use:
 
et <- et(-3, 3, length.out=10)
et$mu <- 0
et$sigma <- 1

model <- function(){
  model({
    fx <- llikNorm(time, mu, sigma)
    dMean <- llikNormDmean(time, mu, sigma)
    dSd <- llikNormDsd(time, mu, sigma)
  })
 }

ret <- rxSolve(model, et)
