Correlation matrix removing insignificant R values
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 help with this? -- View this message in context: http://r.789695.n4.nabble.com/Correlation-matrix-removing-insignificant-R-values-tp4099412p4099412.html Sent from the...

Insignificant variable improves AIC (multinom)?
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 suggests to drop it. I am sure this is due to my lack of understanding of these models but could someone help me out with a pointer what my mistake is? Thanks so much, Werner

insignificant factors in regression model
...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 prediction, sometimes they will produce strange results because their coefficient estimates have large variances. Do we just simply ignore them assuming they are not different from level 0? Or do we exclude them in factors (by treating them as zero's) and refit...

Do we have to control for block in block designs if it is insignificant?
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

Strange p-level for the fixed effect with lme function
...000 F2 -0.008679 0.00616191 659 -1.40855 0.1594 MI 0.009476 0.00258605 659 3.66420 0.0003 As you can see, in exp1 p-levels for the model and for the fixed effects are the same, as thay should be, as far as I know. Yet, in exp2 there is significant p for F2 in the model, but insignificant regarding F2 as fixed factor. How is it possible? I have ran many linear models and those two values correspond (or are the same). Anyway, how can it be to have insignificant effect that is significant in the model? Some strange property of that factor, like distribution? Multicolinearity? Please,...

Tukey, planned contrasts or t-test without ANOVA? What is correct?
...ean 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 levels of months. In the opposite, using a t-test for comparison of independent means (i.e. without using the ANOVA) it demonstrated insignificant differences between the two age classes. What result is correct?

[RFC][LLVM] New Constant type for representing function PLT entries
...on x86, so that’s what inspired the naming. The intended behavior of this IR level change is that at least on x86 or aarch64, the resolved constant could be lowered to something that has the `@plt` syntax, but I suppose other targets could have their own meaning for “the address of this function is insignificant.” > > Abstraction: The IR representation of this probably shouldn’t be too strictly mapped to object file representations. It’s useful to have an IR pattern that can be mapped to relocations on different binary formats, but we don’t want to introduce a state where we have new Constants for i...

comparing glm models - lower AIC but insignificant coefficients
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

[LLVMdev] Avoiding Constant Folding
...front-end be correct; passes like mem2reg will turn your variables into registers if possible anyway). And there's also not much point in trying to keep the bitcode small so as to speed up the optimizers: it will just make your front-end more complicated, while probably the gains (if any) are insignificant. My advice is to keep your front-end as simple as possible. You can run some per-function passes as you output each function, to clean it up and reduce the bitcode size, for example simplifycfg+scalarrepl+instcombine, if memory usage is a problem. Ciao, Duncan.

incomprehesible quirk
...FBSD 4.7, samba 2.2.7 and cups 1.1.15.1_4. When I log onto FBSD with username, password, I see the folders for the printers, home, tmp, etc. but no printer. (Only 1 installed - Epson Stylus Color 900). I can access the shares on FBSD from Win2k, but there is no printer. If I edit smb.conf, with insignificant changes not affecting the printer sections (Printers and Print$) the printer appears. As a side note, I think that the Printer$ section may not be needed if I do not install any Windows or other special drivers - frankly, I don't know why it is even there :(( It appears that editing smb.co...

XEN 3.4.1|HVM|physical disk access
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(?). I tried the following configurations; probably a lot more than this. #disk = [ ''phy:hda1,hda1,r'' ] (comment from xmexample.hvm form /ect/xen) disk = [ ''phy:/dev/sdb1,sda,w'' ] disk = [ ''phy:/dev/sdb1,hda,w'' ] disk = [ ''phy:/dev/sd...

Comparing elements for equality
..., what I am looking to create is a data frame that would be like this id freq var1 var2 1 2 TRUE TRUE 2 3 FALSE FALSE Where freq is the number of times the ID is repeated in the dataframe. A TRUE appears in the cell if all elements in the column are the same for the ID and FALSE otherwise. It is insignificant which values differ for my problem. The way I am thinking about tackling this is to loop through the ID variable and compare the values in the various columns of the dataframe. The problem I am encountering is that I don't think all.equal or identical are the right functions in this case. So,...
