Details
btergm
objects result from the estimation of a bootstrapped TERGM via
the btergm
function. btergm
objects contain the
coefficients, the bootstrapping samples of the coefficients, the number of
replications, the number of observations, the number of time steps, the
original formula, and the response, effects and weights objects that were fed
into the glm
call for estimating the model.
Functions
-
coef(btergm)
: Return the coefficients of abtergm
object. -
nobs(btergm)
: Return the number of observations saved in abtergm
object. -
btergm.se()
: Create a coefficient table from abtergm
objectCreate a coefficient matrix with standard errors and p-values.
This function can create a coefficient matrix with coefficients, standard errors, z-scores, and p-values, based on a fitted
btergm
object. If the argumentprint = TRUE
is used, the matrix is printed to the R console as a formatted coefficient matrix with significance stars instead. Note that confidence intervals are the preferred way of interpretation for bootstrapped TERGMs; standard errors are only accurate if the bootstrapped data are normally distributed, which is not always the case. Various methods for checking for normality for each model term are available, for example quantile-quantile plots (e.g.,qqnorm(x@boot$t[, 1])
for the first model term in thebtergm
object calledx
). -
confint(btergm)
: Return the confidence intervals for estimates in abtergm
object. -
timesteps.btergm()
: Return the number of time steps saved in abtergm
object. -
summary(btergm)
: Summary of a fittedbtergm
object.
