Skewness and Kurtosis
Hi,
in which R-package I could find skewness and kurtosis
measures for a distribution?
I built some functions:
gamma1<-function(x)
{
m=mean(x)
n=length(x)
s=sqrt(var(x))
m3=sum((x-m)^3)/n
g1=m3/(s^3)
return(g1)
}
skewness<-function(x)
{
m=mean(x)
me=median(x)
s=sqrt(var(x))
sk=(m-me)/s
return(sk)
}
bowley<-function(x)
{
q<-as.vector(quantile(x,prob=c(.25,.50,.75)))

Fwd: dse package - load failure
Hello,
Sorry a second time again,
Maybe I have to add that I'm running R under Windows 2000/XP, and
that the download works properly under 1.062 but not under 1.070.

library(fCalendar) timeDate("12.03.2005",format="%d.%m.%Y")
Dear R users,
I have problem with the library fCalendar.
I am not using the US standard format notations. It seems like it is not
possible to have different format than the US standards.
Anyone how knows a way to go around this problem?
Here is the code I enter:
myDate = "12.03.2005"
timeDate(myDate, format = "%d.%m.%Y")
And I get following error message:

Problem setting environment variable in R/zzz.R

environment variable set [1], yet works fine as long as I set TZ.
I figured I could patch this in R/zzz.R and do

farimaSim
Hello!
I installed the fSeries package to get some farima time-series which i tried
with farimaSim, but unfortunately i got always an error. I tried it this way:
> farimaSim(n = 1000, model = list(ar = 0.5, d = 0.3, ma = 0.1), method="freq")
Error in farimaSim(n = 1000, model = list(ar = 0.5, d = 0.3, ma = 0.1), :
... used in an incorrect context
Some ideas?
