Usage

hypothesize(x, null, p = NULL, mu = NULL, med = NULL, sigma = NULL)

Arguments

x

p

The true proportion of successes (a number between 0 and 1). To be used with point null hypotheses when the specified response variable is categorical.

mu

The true mean (any numerical value). To be used with point null hypotheses when the specified response variable is continuous.

med

The true median (any numerical value). To be used with point null hypotheses when the specified response variable is continuous.

sigma

Value

A tibble containing the response (and explanatory, if specified) variable data with parameter information stored as well.

Examples

# NOT RUN {
# Permutation test similar to ANOVA
mtcars %>%
  dplyr::mutate(cyl = factor(cyl)) %>%
  specify(mpg ~ cyl) %>%
  hypothesize(null = "independence") %>%
  generate(reps = 100, type = "permute") %>%
  calculate(stat = "F")

# }
