Hello. I have a large dataset with sales pr month for 56 products with 10 months and i have tried to see how the sales are correlated using cor() This has given me a 56X56 matrix with the R value for each product pair. Most of these correlations are insignificant, and i want only to retain the instances were the R value is significant (for 10 observations it should be above 0.64) Can someone

HI, I am not sure about the ?update() method. You could try this: set.seed(232) mat1<-matrix(sample(1:100,80,replace=TRUE),ncol=8) #with 8 columns dat1<-data.frame(mat1) ?names(dat1)[1]<-"Y" ?fit<-lm(Y~.,data=dat1) res<-coef(summary(fit)) ?res #????????????????

Hi, I am trying to specify a multinomial logit model using the multinom function from the nnet package. Now I add another independent variable and it halves the AIC as given by summary(multinom()). But when I call Anova(multinom()) from the car package, it tells me that this added variable is insignificant (Pr(>Chisq)=0.39). Thus, the improved AIC suggests to keep the variable but the Anova

Hi list, I am building a regression model with categorical predictor variable coded by treatment contrasts. The summary of the regression model shows that some levels are significant while others are not. The significant ones show that they are statistically significant from the basis factor (at level 0). How do we generally deal with those insignificant levels? If they are used for

I am wondering if in a block experimental design (ex. triple square lattice), the block effect was not significant, is it all right not to include the block effect in an empirical model (even though the sampling was done from different blocks)? Or we are forced to control for the block effect in block designs anyway? Thanks, Julia

I posted this question way down at teh end of another thread realted to an error in step, but that was stupid since it really is another matter altogether. I should have posted it separately, as I have now done. The code below creates a data.frame comprising three marginally noisy surfaces. The code below (including a fix courtesy of David Winsemius that avoids a step function error through use

Hello, I ran two lme analyses and got expected results. However, I saw something suspicious regarding p-level for fixed effect. Models are the same, only experimental designs differ and, of course, subjects. I am aware that I could done nesting Subjects within Experiments, but it is expected to have much slower RT (reaction time) in the second experiment, since the task is more complex, so it

Dear R community, I compare mean monthly body temperature between two age classes of turtles overwintering underground. lm(body_tem ~ Month*Year*Age_Class) TukeyHSD(aov(body_tem ~ Month*Year*Age_Class, a)) The Tukey HSD as well as the planned contrasts method showed significant differences between the two age classes, but insignificant differences between the two age classes at the same

I’m going to see if I can summarize the concerns and ideas people have (for my own clarity) and see where we can go on from there. Folks seem to be on board with the idea of introducing some new IR entity that (after linking) *could* be a reference into the PLT, but some

Hi, After a couple of unfortunate hardware failures and some not insignificant amount of work to rebuild two of my DCs, I am trying to check that things are now working correctly.

Hello, I am a new R user and I am trying to estimate some generalized linear models (glm). I am trying to compare a model with a gaussian distribution and an identity link function, and a poisson model with a log link function. My problem is that while the gaussian model has significantly lower (i.e. "better") AIC (Akaike Information Criterion) most of the coefficients are not

Dear all I have undertaken some phylogenetic and non-phylogenetic regressions with gls() in nlme with single preictor variables. A p value is associated with the intercept (upper p value) and another with the predictor variable (lower). Which p value is important? What does it mean if the intercept p value is insignificant but the predictor is still significant? Thanks a lot, and sorry for my

Up to now, the tests have been running with whitespace stripped out. Newlines and tabs are insignificant in HTML, so I figured why bother with them? Now I realize why: they''re significant in pre tags and they also make your code look pretty! I''ve been working to get SRC output to roughly match Tetxile2''s as far as tabs and newlines go.

Hello folks, i do not get access to a physical disk with xen. I would like to install windows xp as hvm to the physical partition /dev/sdb1. I partioned the disk with cfdisk. Filesystem type is Linux (83). In my eyes the filesystem using hvm is insignificant(?).
