A shortcut wrapper function to get the observed test statistic for a t test.
t_stat(x, formula, response = NULL, explanatory = NULL, order = NULL,
alternative = "two_sided", mu = 0, conf_int = FALSE,
conf_level = 0.95, ...)
A data frame that can be coerced into a tibble.
A formula with the response variable on the left and the explanatory on the right.
The variable name in x
that will serve as the response.
This is alternative to using the formula
argument.
The variable name in x
that will serve as the
explanatory variable.
A string vector of specifying the order in which the levels of
the explanatory variable should be ordered for subtraction, where order = c("first", "second")
means ("first" - "second")
.
Character string giving the direction of the alternative
hypothesis. Options are "two_sided"
(default), "greater"
, or "less"
.
A numeric value giving the hypothesized null mean value for a one sample test and the hypothesized difference for a two sample test.
A logical value for whether to include the confidence
interval or not. TRUE
by default.
A numeric value between 0 and 1. Default value is 0.95.
Pass in arguments to {infer} functions.
