ph: Constructor Function for phase type distributions

Description

Constructor Function for phase type distributions

Usage

ph(alpha = NULL, S = NULL, structure = NULL, dimension = 3)

Arguments

alpha

a probability vector.

S

a sub-intensity matrix.

structure

a valid ph structure ("general", "coxian", "hyperexponential", "gcoxian", "gerlang").

dimension

the dimension of the ph structure (if structure is provided).

Value

An object of class '>ph.

Examples

# NOT RUN {
ph(structure = "gcoxian", dim = 5)
ph(alpha = c(.5, .5), S = matrix(c(-1, .5, .5, -1), 2, 2))
# }
