Function Gini or Ineq
Hi listers,
Does it necessary to install any package in order to use the GINI or INEQ
functions.
If I use the following command the R tells me that didn't find the GINI
function.
x<-c(541, 1463, 2445, 3438, 4437, 5401, 6392, 8304, 11904, 22261)
G<-gini(x)
Thanks in advance,
Marcio

Gini coefficient in R
If I use the Ineq library and the Gini function in this way:
>Gini(c(100,0,0,0))
I obtain the result 0.75 instead of 1 (that is the perfect inequality).
I think Gini's formula in Ineq is based on a formula as reported here:
http://mathworld.wolfram.com/GiniCoefficient.html
but in the case of perfect inequality:
x_1=.......=x_n-1 =0
x_n>0
these formula are equal to 1 - 1/n, not to

Compute the Gini coefficient
Hello,
I would like to build a Lorenz curve and calculate a Gini coefficient in order to find how much parasites does the top 20% most infected hosts support.
Here is my data set:
Number of parasites per host:
parasites = c(0,1,2,3,4,5,6,7,8,9,10)
Number of hosts associated with each number of parasites given above:
hosts = c(18,20,28,19,16,10,3,1,0,0,0)
To represent the Lorenz curve:

gini index
Hi.
I have some data from a survey w/c include income data.
Was not quite sure how to generate the gini index on these
data.

Writing R Extensions : A new R package for Gini Index decomposition to prupose
Dear All,
I have developed a programme the anable the decomposition of the Gini index, it complets tha valuable work of Achim Zeileis, the author of the ineq package.
I would like to make it to be part of all R package. How should I proceed.
Must I sent it to the the Core developement team ?
The proogramme is written in R.
Many thanks for your advice,
Best regards,

Gini with bias correction
Hey there,
I was wondering if someone could tell me if there's a package or command
that allows me to compute a GINI coefficient using a vector of weights.
Also the coefficient should be bias corrected.

Fast R implementation of Gini mean difference
I have written the following function to calculate the weighted mean
difference for univariate data (see
http://www.xycoon.com/gini_mean_difference.htm for a related
formula). Unsurprisingly, the function is slow (compared to sd or mad)
for long vectors. I wonder if there's a way to make the function
faster, short of creating an external C function. Thanks very much
for your advice.

how to visualize gini coefficient in each node in RF?
Dear all,
I am working with randomForest package and I am interested in examining the
"Gini importance" measures that are used as a general indicator of feature
relevance. Is there a possibility of getting the Gini measure that is being
estimated in each tree by the output of the getTree() function?
Thanks a lot,

Gini Coefficient
Dear List,
I am unsure if this is specifically a R question or a stats question? I thought i would ask here and if i get no replies it will answer that!
I am trying to calculate Gini coefficients in R, based on a slight modification of the typical equation that i have seen in a paper.

una parte donde se definen las funciones.

Std Err on Concentration measures
Hi,
I'm using the ineq package to calculate some concentration measures (Gini, Herfindal, ...) and I was wondering if there's around also a function to calculate standard error on these measures. If not, is anybody aware of where I can find a reference on this point?
Thanks.

Rpart - best split selection for class method and Gini splitting index
Dear R-users,
I'm working with the Rpart package and trying to understand how the
procedure select the best split in the case the method "class" and the
splitting index "Gini" are used. In particular I'd like to have look to the
source code that works out the best split for un unordered predictor.
Does anyone can suggest me which functions in the sources I should

Compute the Gini coefficient
Hello,
Thank you very much for your help.
How can I draw a Lorenz curve with several replications ?
Here is an example with 4 replications:

[PATCH] Fix keymap for Japanese keyboard
Hi All,
We tested with Japanese keyboard.
Then, the local keys that was not able to be input with a Japanese keyboard was

This patch added the key that was not able to be input to the keymap.
The key that cannot be input is as follows.

hierarchical mixed model
I would like to fit a 2-level mixed model:
yit=a+a[i]+a[it] +(b+b[i]+b[it])*xit+eps[it]
However, the variance of the second level components should depend on the group, i.e. sigma for a[it] and b[it] should be [i] specific.
I do not know whether this is conceptually right in the mixed model context...
In case it stands, how should the formula look like?
Also, the data are unbalanced with

Theil decomposition
I came across the package 'ineq' that computes a variety of inequality measures (e.g. gini, theil etc). I want to compute the Theil index (racial segregation) and decompose the total into sub-components (by geog levels). I think the package doesn't report the decomposition (correct me if I'm wrong). Just wonder is that available elsewhere?

Executing an windows application installer that check for wi ndow s version?
Hi All
Andrily, Thanks for the information. I've tried setting the config file. YIt doesn't work. I've checked with the application support. According to them, the OS check is done by InstallShield product functionality. Anyone has any idea how Installshiled detects the version of os ( can't find such info on their website!) and how we can workaround it.
Thanks again

Random intercept-slope correlation (nlme)
Dear list members,
I am working with a multilevel growth curve, that in its simplest form goes
like follows:
Yit = Ai + Bi t + eit (the error term is assumed to follow an AR(1)
autorregressive process)
One major topic in my research is the convergence in the values of Y over
time. Thus, I am interested in the relationship between the random effects
for the intercept and the slope, and I

Multiple Lorenz curves in one diagram - populations with different "n"
Dear R users,
I'm using the "ineq" package to calculate the values of Gini and Lorenz coefficients and to and plot Lorenz graph.
I want to plot on the same diagram, curves from two different populations, that have different "n".
How can I do this?
Best regards,
