Description Usage Arguments Details Value See Also Examples

Empircal distribution function of left truncated data with known distribution.

1 |

`x` |
a numerical vector of data values |

`distn` |
character string naming the distribution function |

`parm` |
list of distribution parameters |

`H` |
a treshold value |

`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`

.

A function of class "stepfun".

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))
