x |
A data frame that can be coerced into a tibble. |
null |
The null hypothesis. Options include |
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 |
The true standard deviation (any numerical value). To be used with point null hypotheses. |
A tibble containing the response (and explanatory, if specified) variable data with parameter information stored as well.
# hypothesize independence of two variables
gss %>%
specify(college ~ partyid, success = "degree") %>%
hypothesize(null = "independence")
# hypothesize a mean number of hours worked per week of 40
gss %>%
specify(response = hours) %>%
hypothesize(null = "point", mu = 40)
