confint.galamm: Confidence intervals for model parameters

In galamm: Generalized Additive Latent and Mixed Models

Confidence intervals for model parameters

Description

Confidence intervals for model parameters

Usage

## S3 method for class 'galamm'
confint(object, parm, level = 0.95, method = "Wald", ...)

Arguments

object	An object of class galamm returned from galamm.
parm	Parameters for which to compute intervals. Use "theta" to get all variance parameters, "beta" to get all fixed regression coefficients, "lambda" to get all factor loadings, and "weights" to get all weights. The parameter can also be given as a numeric vector with indices specifying the parameters. When given as characters, the arguments are case sensitive.
level	Decimal number specifying the confidence level. Defaults to 0.95.
method	Character of length one specifying the type of confidence interval. Currently only "Wald" is available. The argument is case sensitive.
...	Other arguments passed on to other methods. Currently not used.

Value

A matrix with the requested confidence intervals.

See Also

fixef.galamm() for fixed effects, coef.galamm() for coefficients more generally, and vcov.galamm() for the variance-covariance matrix. confint() is the generic function.

Examples

# Poisson GLMM
count_mod <- galamm(
  formula = y ~ lbas * treat + lage + v4 + (1 | subj),
  data = epilep, family = poisson
)

confint(count_mod, parm = "beta", level = .99)
