modello (version 0.1.1)

ldlaplace.modello_number: Laplace Distribution: log-density

Description

Considering a Laplace Distribution calculates the log-density $$ld = log(0.5) + log(\lambda) - \lambda * |y - \mu|$$

Usage

# S3 method for modello_number
ldlaplace(y, mu, lam)
ldlaplace(y, mu, lam)

Arguments

y

observations, numeric or reference object of class 'number'

mu

location parameter, numeric or reference object of class 'number'

lam

rate parameter, numeric of reference object of class 'number'

Value

Returns a 'numeric' or a reference object of class 'number'

Examples

# NOT RUN {
modello.init(10, 10, 10, 10)
y = number(rnorm(10))
ld = ldlaplace(y, .k(0), .k(1))
print(ld)
print(ld$v)
modello.close()
# }
