edf: Empirical distribution function

In truncgof: GoF tests allowing for left truncated data

Description

Empircal distribution function of left truncated data with known distribution.

Usage

edf(x, distn = NA, parm = NA, H = NA)

Arguments

x	a numerical vector of data values
distn	character string naming the distribution function
parm	list of distribution parameters
H	a treshold value

Details

edf is a version of ecdf allowing left truncated data. If distn is not assigned all other arguments except x are ignored and the result is exactly the same as of ecdf.

Value

A function of class "stepfun".

ecdf, dplot

Examples

set.seed(123)
treshold <- 10
xc <- rlnorm(30, meanlog = 2, sdlog = 1)    # complete sample
xt <- xc[xc >= treshold]                    # truncated sample

# the results are identical:
plot(edf(xc))
plot(ecdf(xc))

# considering truncated samples:
plot(edf(xt))   # wrong plot
plot(edf(xt, "plnorm", list(meanlog = 2, sdlog = 1), H = 10))
