Dear all, I would be glad if someone could tell me if Tukey HSD (function of stats library) accept the NA values and could correct the unbalanced design (different number of sample in each group) Thanks for help Alice Le Bars

Dear all, This is a pure statistical question, not necessarly related to R. I could not find it in literature. Suppose I'm intersted in a parameter rho, say, equal to: r=beta1/beta2, where beta1 and beta2 come from a linear model y=beta0+beta1X1+beta2X2+.... Fitting the model I can get the (biased) estimate of r=b1/b2, where b1 and b2 are the estimates in the regression model; I can get the

The help for the round function states: round rounds the values in its first argument to the specified number of decimal places (default 0). Note that for rounding off a 5, the IEEE standard is used, ``go to the even digit''. Therefore round(0.5) is 0 and round(-1.5) is -2. Could someone provide a reference for this standard? Thanks, Anne ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Anne E.

Dear colleague: Actually that is what is done. When using the z-test between proportions in two different groups, or using chi-squared to test the null hypothesis of equal proportions of two or more groups, the null hypothesis is that H0: p1=p2=p3.....=p where this p is the pooled proportion, the proportion in the summed groups = n1+n2+n3+..../N1+N2+N3.... in the z-test between two

Hi, i am working on a data set with EDA. That includes QQ-Plots of residuals vs expected normal distribution. What puzzles me is that the range of ordinate and abscissae is so different: while the theoretical quantiles range from [-2, 2] the sample quantiles on the ordinate do extent from [-20, 50]. Quite obviously some kind of transformation is done. Although i intensively RTFM i could not

Is there a "canned" function in R for finding the standard error of the mean? I have tried > sem <- function(x) c(mean =mean(x), + SEM = stdev(x)/sqrt(length(x))) > sem(pnet.lai) Error in sem(pnet.lai) : couldn't find function "stdev" It looks like there is no stdev function in R Thanks, Kirk Kirk R.

Hi I try to implement a simple 2-factorial repeated-measure anova in the lme framework and would be grateful for a short feedback -my dependent var is a reaction-time (rt), -as dependent var I have -the age-group (0/1) the subject belongs to (so this is a between-subject factor), and -two WITHIN experimental conditions, one (angle) having 5, the other 3 (hands) factor-levels;

Hi, I am getting some strange results using round - it seems that it depends if the number before the decimal point is odd or even .... For example: > round(1.5)[1] 2> round(2.5)[1] 2 While i would expect that round(2.5) be 3 and not 2. Do you have any explanation for that? I really appreciate your input, Monica

> I think what you're seeing is > https://en.wikipedia.org/wiki/Loss_of_significance. Almost. All the results in the OP's summary are reflections of finite precision in the analytically exact solution, leading to residuals smaller than the double precision limit. The summary is correctly warning that it's all potentially nonsense, and indeed the only things you can trust are

Indeed (version-specific). With R 3.4.1 on linux, I get coefficients and residuals that are numerically exact, F-statistic = NaN, p-value = NA, R-squared = NaN, etc. All of which is what ought to happen, given that the response variable (y) is not actually variable. ---JRG John R.

Hi, I was setting up a new system for testing Dovecot 1.0. My old one is using 0.99 and was set up quite a time ago, so I had to consult the documentation. I needed several attempts until it worked and that was because the designated maildir directory /server/mail/jrg/Maildir was completely empty. Upon login the server exited and wrote the following to the log: POP3(jrg): Ambiguous mail location

I''m using a plugin which adds a method to ActiveRecord::Base http://similetimelinerailshelper.googlecode.com/svn/trunk/simile_timeline/ This adds an "acts_as" type declaration to the Models, via the file in vendor/plugins/simile_timeline/lib/simile_timeline.rb Rails is working with these declarations, and they are being used successfully in ''regular

Hi -- I had a pretty quick R question since unfortunately I have not been able to find an answer on Google. It shouldn't take much more than a minute to answer. I'm trying to add up the major gleason grade and minor gleason grade for an analysis of patients with prostate cancer. One column has values under "Major Gleason" and another column has values under "Minor

You must create a output filter. Edit /etc/printcap and add your client printer like this: ... PC-PRINTER:\ :sd=/var/spool/lpd/PP01:\ :mx#0:\ :lp=/dev/null:\ :if=/var/spool/lpd/Filter/PP01:\ :sh: ... Adjust the printcap parameters as needed (spool directory, directory to find the filter script). Make sure the lpd can access the directory. Consult your manual. Now create the filter

Speaking conservatively, I would de-rate that number by 50%, or in other words: 0.5*283000/5000=28.3 kb/sec. This to account for various overheads

Hi Folks, I have repeated measures for data on association time (under 2 acoustic condtions) in male and female frogs as they grow to adulthood (6 timepoints). Thus, two within-subject variables (Acoustic Condition: 2 levels, Timepoint: 6 levels) and one between-subject variable (Sex:male or female). I am pretty sure my distributions depart from normality but I would first like to simply run a
