Wald confidence intervals for the intercept and dyadic-covariate
coefficients of an ame_als fit, built from the conditional
sandwich covariance (vcov.ame_als).

These intervals are a fast convenience. They are conditional (the
additive and multiplicative effects are held fixed) and therefore
anti-conservative, and they cover only the regression coefficients the
sandwich covariance is defined for -- not the node-covariate, additive or
multiplicative parameters. For fully-propagated intervals on all parameters,
use ame_als_bootstrap and confint.boot_ame.
ame_als_bootstrap for bootstrap intervals on all
parameters.
