...eply. I am using Friedman racing test. According the the book "Pratical Nonprametric Statistic" by WJ Conover, after computing the statistics, he suggested to use chi-squared or F distribution to accept or reject null hypothesis. After looking into the source code, I found that R uses chi-sqaured distribution as below: PVAL <- pchisq(STATISTIC, PARAMETER, lower = FALSE) but still I cant figure out why they are using this pschisq insted of dchisq.

I am working with a RCB 2x2x3 ANCOVA, and I have noticed a difference in the calculation of sum of squares in a Type III calculation. Anova output is a follows: > Anova(aov(MSOIL~Forest+Burn*Thin*Moisture+ROCK,data=env3l),type=3) Anova Table (Type III tests) Response: MSOIL Sum Sq Df F value Pr(>F) (Intercept) 22.3682 1 53.2141 3.499e-07 *** Forest

Dear Rs: outer(1:3, 1:3, function(df1, df2) qf(0.95, df1, df2)) I compare this F distribution results with the table, the answers were perfect. But I need to see for chi-sqaured distribution. When I employed the similar formula outer(1:3, 1:3, function(df1, df2) qchisq(0.95, df1, df2)) , I am getting unexpected results. I need to see the following values: p=0.750 ..... 1 1.323 2 2.773 3 4.108 Thanking you Prasanna Prasanna Balaprakas...

I wanna to do a Regression type 2 or Regression with X measured with error....anybody knows how can i make it in R?? thanks! -- View this message in context: http://r.789695.n4.nabble.com/Regression-type-2-x-measured-with-error-tp3251875p3251875.html Sent from the R help mailing list archive at Nabble.com.

All: Any ideas on how to do variance component estimation, or at least get Expected Mean Sqaures out of the modeling commands. Thanks.

Hello, I previously sent this message which was stripped off due to HTML mail. Sorry! Thanks. Hello All, I am new to the list. I have been learning to use R recently and its been great to see so much help available. However I must admit, I have stumbled upon a problem with correlation matrices and was hoping if someone could help. I have an excel workbook with a sheet per drug. Each sheet

I've put two packages for R on my home page at http://www.xs4all.nl/~jhckx/R/. The "pcnt" package is for multiway percentage tables. I've posted a first effort called "ctab" on this group and a request for enhancing "ftable" with percentages on the wishlist. The "mcl" package is for estimating multinomial logistic models using conditional logistic

Hi everybody I have a questionnaire with a lot of questions that allow for more than one option to be chosen (like a tickbox in a html form). The data captured on a mobile device and is supplied in a format where every option is a separate variable (logical). I want to develop a generic function to process these questions. As part of the analysis I want make a matrix of the p-value from the

hi I''m making a chess board app in Rails using the scriptaculous drag and drop stuff. A couple of questions, I am having trouble putting the chess pieces in the correct place - simply it seems that when i make somethign draggable it changes its positioning to relative - not so good for putting pieces on a board. Why is this ? Also i can''t see an OnDrop callback in the API

Hello everybody, Could someone please send me a very simple example using Fortran from R? Say pass a value to an executable and get the result in R. Actually it seems it may be possible to call an *.f file ?? or I am wrong again? The manual is very terse on the subject. Thank you very much Stephen Elijah -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help

Hi R- User I have very big data set (5000 rows). I wanted to make classes based on a column of that table (that column has the data which is continuous .) After converting into different class, this class would be Unique ID. I want to run regression for each ID. For example I have a data set > dput(dat) structure(list(ID = c(0.1, 0.8, 0.1, 1.5, 1.1, 0.9, 1.8, 2.5, 2, 2.5, 2.8, 3, 3.1, 3.2,
