Re: [R] Generating series of distributions with the same skewness and different kurtosis or with same kurtosis and different skewness?

Well, let's take the Beta distribution for example. See http://en.wikipedia.org/wiki/Beta_distribution for the formulae of skewness and kurtosis. We can fix the skewness at, say, 2 and let alpha = 1, then solve beta from the equation of "skewness = 2", you will get beta = 1.8164966 or 0.1835034 app

Hi all, When I try to sum a few columns in a data frame (which has NA’s randomly distributed as elements), I am not able to get the summing operation to ignore the NA’s. Let me explain with the following code :   a<-structure(list(a1 = c(NA, 2, 3, NA, 5, 6, NA, 8,

Re: [R] xyplot problem

xyplot will pass a vector of indices through the subscripts argument to the panel so try this: xyplot(y ~ x | grp, panel = function(x, y, subscripts, ...) { panel.xyplot(x, y, cex = sz[subscripts], ...) } ) On Tue, Sep 23, 2008 at 9:27 AM, Pascal A. Niklaus <[EMAIL PROTECTED]> wrote: > H

[R] Generating series of distributions with the same skewness and different kurtosis or with same kurtosis and different skewness?

Dear R users, I hope to explain the concepts of skewness and kurtosis by generating series of distributions with same skewness and different kurtosis or with same kurtosis and different skewness, but it seems that i cannot find the right functions. I have searched the mailing list, but no answ

Is this what you want? xyplot(y~x | grp, panel = function(x, y, ...){ panel.xyplot(x, y, cex = 1:3, pch = 19, col = 2:5) }) On Tue, Sep 23, 2008 at 10:27 AM, Pascal A. Niklaus <[EMAIL PROTECTED]> wrote: > Hi all, > > I am trying to produce some panels with dots in an X/Y p

Re: [R] Statistical question re assessing fit of distribution functions.

Thanks Timur While assessing whether or not the best option would be a normal distribution (it won't be, the data in this case LOOKS more poisson, or if I explude the first week of results, a negative exponential; and in my other case, cauchy is more likely), I really need a test that can be appl

Darrin, what version of R are you using have the same question. I have been using the gbm package without problem with R 2.7.1. but I recently switched computers and downloaded 2.7.2. I used the following code, which works fine on my old computer with 2.7.1 but I get an error with the new versio

[R] xyplot problem

Hi all, I am trying to produce some panels with dots in an X/Y plane where the diameter of the dots indicates a Z value (like e.g. earthquake maps where dot sizes indicate magnitudes and X/Y the location). This works fine with xyplot, e.g.: xyplot(1:3~1:3,cex=1:3,pch=16) However, when I do th
