VGAM (version 1.1-4)

eCDF: Empirical Cumulative Distribution Function

Description

Returns the desired quantiles of quantile regression object such as an extlogF1() or lms.bcn() VGLM object

Usage

eCDF.vglm(object, all = FALSE, …)

Arguments

object

an object such as a vglm object with family function extlogF1 or lms.bcn.

all

Logical. Return all other information? If true, the empirical CDF is returned.

…

additional optional arguments. Currently unused.

Value

A vector with each value lying in (0, 1). If all = TRUE then a 2-column matrix with the second column being the tau values or equivalent.

Details

This function was specifically written for a vglm object with family function extlogF1 or lms.bcn. It returns the proportion of data lying below each of the fitted quantiles, and optionally the desired quantiles (arguments tau or percentiles / 100 in the family function). The output is coerced to be comparable between family functions by calling the columns by the same names.

Examples

# NOT RUN {
fit1 <- vglm(BMI ~ ns(age, 4), extlogF1, data = bmi.nz)  # trace = TRUE
eCDF(fit1)
eCDF(fit1, all = TRUE)
# }
