Re: [R] how to draw a 45 degree line on qqnorm() plot?

Thank you. I didn't know scale(). Qqline passes through 1st and 3rd quantiles, It doesn't seem very useful to me. I thought a diagnol line will demonstrate the deviation from a standard normal. Correct me if I was wrong. Thanks. On Apr 3, 2005 2:40 AM, [EMAIL PROTECTED] [EMAIL PROTECTED]

[R] wrong signs using MNP.

Dear Bill, You might want to check whether the parameterization of MNP differs from the book you mention, which I don't have. In particular, I would check how the choice specific covariate is calculated. More importantly, I would also make sure that your chain has converged. Based on my

Re: [R] French Curve

Thanks so much, Martin, Martyn, Marc and others for your insightful input on French Curve. From how the chemist is using the French Curve now, it seems he is using for spline. Basically, he has two curves from spectrometry data. To find the area underneath one curve without the noise area, he

[R] Generating a binomial random variable correlated with a normal random variable

Hi All: I would like to generate a binomial random variable that correlates with a normal random variables with a specified correlation. Off course, the correlation coefficient would not be same at each run because of randomness. I greatly appreciate your input. Ashraf

[R] 'skewing' a normal random variable

Hi All; The following question is directed more to statisticians on the list. Suppose I have a normal random variable. Is there a transformation that I can apply so that the new variable is slightly positively skewed. I greatly appreciate your help. Ashraf

RE: [R] how to draw a 45 degree line on qqnorm() plot?

Remember this is just a diagnostic procedure and all you are really looking for is whether the normal scores plot is pretty straight. The reason for anchoring the guiding line at the quartiles is really the same reason that boxplots use quartiles for the central chunk. You don't want the guiding

[R] RDCOMServer for R 2.0.1 + Windows ?

Has anyone managed to get this working? Here's what I did: I got the binary build for R2.0.1 from the Omegahat download page, and made a small change to the registerClassID function ( to make it use the right path to RDCOMServer.dll). Then I tried to replicate the simple TTest example from the

[R] Using kmeans given cluster centroids and data with NAs

Hello Tom, Thanks for the reply. Unfortunately I do have many NAs in my data as not all vertical temperature profiles penetrated to the same depth level. In fact if I simply use na.omit my data matrix is reduced from 4977 to 480 observations, so such a simple solution is not very helpful I'm

I think the box.cox function in package car can do this. x - rnorm(1000) hist(x) library(car) hist(box.cox(x, p=0.5)) Play around with different powers. Best, Matthias -Ursprüngliche Nachricht- Von: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Im Auftrag von Ashraf Chaudhary
