Fitted Value Pareto Distribution
I would like to fit a Pareto Distribution and I am using the following codes.
I thought the fitted (fit1) should be the fitted value for the data, is it
correct? As the result of the "fitted" turns out to be a single value for
all.
fit=vglm(ycf1 ~ 1, pareto1(location=alpha), trace=TRUE, crit="c")
fitted(fit)
The result is

Fitting data to Pareto distribution
Dear All,
I am trying to fit some data to a Pareto distribution and would like to
estimate the parameters with the fitting. I have come across some options so
far. Unfortunately I haven't managed to get any of them to make the right
fits (as is evident when I check with the goodness of fit). One such option
is:

VGAM package released on CRAN
Dear useRs,
upon request, the VGAM package (currently version 0.7-1) has been
officially released on CRAN (the package has been at my website
http://www.stat.auckland.ac.nz/~yee/VGAM for a number of years now).
VGAM implements a general framework for several classes of
regression models using iteratively reweighted least squares
(IRLS). The key ideas are Fisher scoring, generalized linear

ECDF, distribution of Pareto, distribution of Normal
Hello all,
I would like to plot the emperical CDF, normal CDF and pareto CDF in the

simulation from pareto distn
Dear all,
I am trying to simulate from truncated Pareto distribution. I know there is
a package called PtProcess for Pareto distribution...but it is not for
truncated one. Can anyone please help me with this?
Thanks in advance.

rmutil parameters for Pareto distribution
In https://en.wikipedia.org/wiki/Pareto_distribution, it is clear what the
parameters are for the pareto distribution: *xmin *the scale parameter and
*a* the shape parameter.
I am using rmutil to generate random deviates from a pareto distribution.
It says in the documentation that the probabilty density of the pareto
distribution
The Pareto distribution has density

How can I simulate Pareto distribution in R?
Hi, guys,
I need to simulate Pareto distribution. But I found 'rpareto' didn't exist in R. And it seems that Pareto distribution don't have mathematical relationships with other distributions. What can I do?
Thanks a lot.

CDF for pareto distribution
Hi, I would like to use the following codes to plot the CDF for pareto
distribution. Before doing this, I have plot the emperical one.
x <- seq(1.6, 3, 0.1)
lines(x,pgpd(x, 1.544,0.4477557,), col="red")
Could anyone give me some advice whether the above codes are correct?
Many thanks.

ggplot2 Pareto plot (Barplot in decreasing frequency)
Hi all
I have a large dataframe with (among others) a categorical variable of 52
levels and would like to create a barplot with the bars ordered in
decreasing frequency of the levels. I belive it is referred to as a pareto
plot.
Consider a subset where I keep only the categorical variable in question.

Is there a function to plot a Pareto diagram?
Hi-
Is there a quick way to plot a Pareto diagram?
I couldn't find one. I'm being forced to do some pretty weird stuff,
with awk and all, to extract data in order to plot the frequency of
qualitative data from a larger set. Perhaps it's just my GNUrance.
I mean, one day, if I have time, I might even write a generic Perl script,
but right now, it doesn't look too good on the

GARCH (1 , 1), Hill estimator of alpha, Pareto estimator
Dear R users,
Could you please help me out. I am in trouble as I am unable to model graphs
to explain the GARCH (1 , 1) model, the Hill estimator (of alpha), and the
Pareto estimator.
I just got introduce to R. I am working on a paper which must be worked from
R.

KS and AD test for Generalized PAreto and Generalized Extreme value
Dear R helpers,
I need to use KS and AD test for Generalized Pareto and Generalized extreme value.
E.g. if I need to use KS for Weibull, I have teh syntax
ks.test(x.wei,"pweibull", shape=2,scale=1)
Similarly, for AD I use
ad.test(x, distr.fun, ...)
My problem is fir given data, I have estimated the parameters of GPD and GEV using lmom. But I am not able to find out the distribution

Truncated Normal Distribution and Truncated Pareto distribution
Dear R helpers,
I have a bimodal dataset dealing with loss amounts. I have divided this dataset into two with the bounds for the first dataset i.e. dataset-A being 5,000$ to 100,000$ and the dataset-B deals with the losses exceeding 100,000$ i.e. dataset-B is left truncated.
I need to fit truncated normal disribution to dataset - I having lower bound of 5000 and upper bound of 100,000. While I

Bug in VGAM z value and coefficient ?
Dear,
When i multiply the y of a regression by 10, I would expect that the
coefficient would be multiply by 10 and the z value to stay constant. Here
