Tidy Distribution Summary Statistics Tibble

Source: R/tidy_distribution_summary_tbl.R
tidy_distribution_summary_tbl.Rd

This function returns a summary statistics tibble. It will use the y column from the tidy_ distribution function.

Usage

tidy_distribution_summary_tbl(.data, ...)

Arguments

.data

The data that is going to be passed from a a tidy_ distribution function.

...

This is the grouping variable that gets passed to dplyr::group_by() and dplyr::select().

Value

A summary stats tibble

Details

This function takes in a tidy_ distribution table and will return a tibble of the following information:

  • sim_number

  • mean_val

  • median_val

  • std_val

  • min_val

  • max_val

  • skewness

  • kurtosis

  • range

  • iqr

  • variance

  • ci_hi

  • ci_lo

The kurtosis and skewness come from the package healthyR.ai
