Parametric bootstrap Wald test

Description

Parametric bootstrap Wald test

Usage

pbWald(mod, mod_null, B = 1000, robust = FALSE)

Arguments

mod

an object of class bbdml

mod_null

an object of class bbdml, should be nested within mod

B

Integer. Defaults to 1000. Number of bootstrap iterations.

robust

Should robust standard errors be used? If not, model-based standard arras are used. Logical, defaults to FALSE.

Value

P-value from parametric bootstrap Wald test.

Examples

data(soil_phylum_small_otu1)
mod1 <- bbdml(formula = cbind(W, M - W) ~ DayAmdmt,
phi.formula = ~ DayAmdmt,
data = soil_phylum_small_otu1)

mod2 <- bbdml(formula = cbind(W, M - W) ~ 1,
phi.formula = ~ 1,
data = soil_phylum_small_otu1)
pbWald(mod1, mod2, B = 50)
