Copula.Markov (version 2.9)

Joe.Markov.MLE.binom: Maximum Likelihood Estimation and Statistical Process Control Under the Joe Copula

Description

The maximum likelihood estimates are produced and the Shewhart control chart is drawn with k-sigma control limits (e.g., 3-sigma). The dependence model follows the Joe copula and the marginal (stationary) distribution follows the binomial distribution.

Usage

Joe.Markov.MLE.binom(Y, size, k = 3, plot = TRUE, GOF=FALSE)

Arguments

Y

vector of observations

size

number of binomial trials

k

constant determining the length between LCL and UCL (k=3 corresponds to 3-sigma limit)

plot

show the control chart if TRUE

GOF

show the model diagnostic plot if TRUE

Value

p

estimate, SE, and 95 percent CI

alpha

estimate, SE, and 95 percent CI

Control_Limit

Center = n*p, LCL = mu - k*sigma, UCL = mu + k*sigma

out_of_control

IDs for out-of-control points

Gradient

gradients (must be zero)

Hessian

Hessian matrix

Eigenvalue_Hessian

Eigenvalues for the Hessian matrix

KS.test

KS statistics

CM.test

CM statistics

log_likelihood

Log-likelihood value for the estimation
