coefEmax: Extract Emax model parameter estimates

Description

Extract Emax model parameter estimates. MLE for fitEmax. Matrix of MCMC generated parameters for fitEmaxB.

Usage

# S3 method for fitEmax
coef(object, ...)
	# S3 method for fitEmaxB
coef(object, local=FALSE, ...)
	# S3 method for emaxsim
coef(object, ...)
	# S3 method for emaxsimB
coef(object, local=FALSE, ...)

Value

Vector of MLE estimates of model parameter from fitEmax. Matrix of MCMC generated parameters for fitEmaxB. Matrix with posterior median parameter estimates for each emaxsimB simulation: (led50,lambda,emax,e0) or (led50,emax,e0). For emaxsim, a list is returned with the model type fit for each simulation, and a matrix with the corresponding model coefficients. The order of the parameters is given in the emaxsim documentation.

Arguments

object: Output of Emax fitting function
local: When a prior distribution of type 'emaxPrior' was used to create the object, specifying local=TRUE will output the local 'difTarget' parameter estimates.
...: No additional inputs supported
