Functions in infer (0.3.0)

hypothesize

Declare a null hypothesis
chisq_test

A tidier version of chisq.test for goodness of fit tests and tests of independence.
p_value

Compute the p-value for (currently only) simulation-based methods get_pvalue() is an alias of p_value
%>%

Pipe
conf_int

Compute the confidence interval for (currently only) simulation-based methods
infer

infer: a grammar for statistical inference
generate

Generate resamples, permutations, or simulations based on `specify` and (if needed) `hypothesize` inputs
chisq_stat

A shortcut wrapper function to get the observed test statistic for a chisq test. Uses stats::chisq.test, which applies a continuity correction.
print.infer

Print methods
rep_sample_n

Perform repeated sampling
calculate

Calculate summary statistics
t_stat

A shortcut wrapper function to get the observed test statistic for a t test
specify

Specify the response and explanatory variables with specify also converting character variables chosen to be factors
set_params

To determine which theoretical distribution to fit (if any)
visualize

Visualize the distribution of the simulation-based inferential statistics or the theoretical distribution (or both!)
t_test

A tidier version of t.test for two sample tests
