Get a table of quantile intervals ("qi") corresponding to a vector of interval widths.

These intervals are also called "equal-tailed intervals". An interval of width x ranges from the 0.5 - x / 2 quantile to the 0.5 + x / 2 quantile.

Usage

widths_to_qi_table(widths, quantile_tol = 10)

Arguments

widths

Vector of interval widths. All entries must be between 0 and 1, inclusive. Duplicate entries are ignored.

quantile_tol

Round quantile level values to this many decimal places, to avoid problems with floating point number equality comparisons. Passed as the digits argument to base::round(). Default 10.

Value

A table of available intervals, as a tibble, with columns .lower_quantile, .upper_quantile, and .width, that give the bounds and the widths of the requested intervals.
