...---------------------------------------------------------------. Have a look at the two variables age and sport. In spss the values (-99) in age is a missing, as well as the value (9) in sports. As you can see - the information about the missings in R is lost. What can I do? Many Thanks Christine Christmann

I have a data set w/ an ordinal response taking on one of 10 categories. I am considering using polr to fit a cumulative logits model. I previously fit the model in SAS (using proc logistic) which provides a test for the proportional odds assumption (p < 0.001 for the test). Are there simple diagnostic plots that can be used to look at the validity of this assumption and possibly help w/

...character like "miss" would be even better. To transform them into "NA" as the sysmis data from Spss is transformed automatically, would be an other alternative. Unfortunately I don't know if any of these options are possible. Could you help me out? Many thanks. Christine Christmann --

...response by Pfr. Ripley to a inquiry regarding the ability of rpart to handle ordinal responses in 2003. At that time rpart was unable to implement an algorithm to handle ordinal responses. Has there been any effort to rectify this in recent years? Thanks! Stacey On Mon, 2 Jun 2003, Andreas Christmann wrote: > >>> 1.

Dear all, Last autumn there was some discussion on the list of the warning Warning message: fitted probabilities numerically 0 or 1 occurred in: (if (is.empty.model(mt)) glm.fit.null else glm.fit)(x = X, y = Y, when fitting binomial GLMs with many 0 and few 1. Parts of replies: "You should be able to tell which coefficients are infinite -- the coefficients and their standard errors will

They're very pretty when they're all lit up :) http://www.hotlavasystems.com/ I also saw an interesting low-cost 'fat blade' server called 'skimpy' by http://www.christmann.info/products/show/65 As they say on their site - don't search for images on google using that term! They also had a 64-port 1U 10Gbe switch: that's a lot of ports in 1U! They had it set up with a 3U server containing three dual 8-core motherboards and an array of 64 600G SAS SSDs, plus a c...

Hello, I know I should get rid of the problem by my own, but unfortunally I failed. So I ask: I`ve a subnet of win9x and WinNT clients connecting to our Linux file server (no more servers in this subnet) via samba 2.02. All win95 can see and mount services of the Samba server. But win98 and WinNT can only see the server but can not connect to a service. I`ve no encryption and security= user in

Hello, I've a problem known especially to german speaking users (and other nationalities using special characters). I'm using Samba 1.9.18 and a linux 2.0.35 kernel I want to create a directory or file with a name containing german umlaute from the win95 client so that I can see it on the linux machine with the equal characters I've used under win95. On the win95 machine the new

Hello, I've tried to make out of my samba 2.0.3 server a logon server. I' ve set domain logons = Yes domain master = No local master =Yes os level = 65 preferred master =Yes but: wins support = No I made a share as recommended [netlogon] and place there a logon.bat. The logon.bat contains net use z: \\servername\public for testing if the logon.bat is excecuted by login to the server.

Hello, yesterday I've changed my password system to encrypted password because somebody wanted to log in with win98 notebook. And I wanted not to make the change in registry of the notebook. Therefore I set encrypted password = Yes, added and enabled the user with smbpasswd -a -e <account>. After this change he can log in via dhcp in our network. But in the next morning I've

Hello, I'm using samba2.02 and shadowed passwords. I' m on the way to migrate from plaintext to encrypted passwords. Therefore I've set the parameter update encrypted to "Yes". After everyone has logged in I will set this parameter to "No" again and set encrypted passwd = Yes. So far, so good. But three questions are remaining for me: a) what to do with those who
