`eta_squared()`

family now indicate the type of sum-of-squares used.`rank_biserial()`

estimates CIs using the normal approximation (previously used bootstrapping).

objects as input.`standardize_parameters()`

`oddsratio()`

and`riskratio()`

- order of groups has been changed (the*first*groups is now the**treatment group**, and the*second*group is the**control group**), so that effect sizes are given as*treatment over control*(treatment / control) (previously was reversed). This is done to be consistent with other functions in R and in`effectsize`

.

) in a passed formula.`eta_squared()`

family of functions gains a`verbose`

argument.`verbose`

argument more strictly respected.`glass_delta()`

) - argument`parameters`

has been dropped.

for post-hoc correctly standardizes transformed outcome.Setting

`two_sd = TRUE`

in`standardize()`

and`standardize_parameters()`

(correctly) on uses 2-SDs of the predictors (and not the response).`standardize_info()`

/`standardize_parameters(method = "posthoc")`

work for zero-inflated models ( #135 )`standardize_info(include_pseudo = TRUE)`
