edf {truncgof} | R Documentation |
Empircal distribution function of left truncated data with known distribution.
edf(x, distn = NA, parm = NA, H = NA)
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))
