structural equation modeling in sem, error, The model has negative degrees of freedom = -3, and The model is almost surely misspecified...
Hi all, I am attempting to learn my way through the sem package by constructing a simple structural model for some of my data on bird diversity, abundance, and primary productivity. I have constructed a covariance matrix between these variables as per the following: >S_matrix = matrix(c( >+ 0.003083259, 0, 0, >+ 0.143870284, 89.7648490, 0, >+ 0.276950919,

Ruby 1.8.7 + Rails 2.3.2 + TLS = Where's the documentation?
After spending a few hours reading dozens of blogs and tutorials I am still stumped. Numerous sites mention ruby 1.8.7 and rails 2.3 supporting TLS out of the box. However, I can not find any documentation on setting this up to send emails correctly. Furthermore, after attempting to send emails using Gmail and TLS i get the following error: 530 5.7.0 Must issue a STARTTLS command first.

The constant part of the log-likelihood in StructTS
Dear all, I'd like to discuss about a possible bug in function StructTS of stats package. It seems that the function returns wrong value of the log-likelihood, as the added constant to the relevant part of the log-likelihood is misspecified. Here is an simple example: > data(Nile) > fit <- StructTS(Nile, type = "level") > fit$loglik [1] -367.5194 When computing the

Growth Curves with lmer
...pt model using lmer lmer(y ~ 0+t+t.squared+t:treat+t,squared:treat+(0+t+t.squared+t:treat +t,squared:treat | classifier) The fixed effects are similar to the pooled regression, but most of the random effects for t and t:treat are implausible (negative). What's wrong with the lmer model? Did I misspecify something? Greetings, Michael

Strange behaviour of methods::slot() when returning a tibble
...However, when I call slot(object, name) where 'name' is an slot that contains a tibble I get the following warning: Warning message: `...` is not empty. We detected these problematic arguments: * `needs_dots` These dots only exist to allow future extensions and should be empty. Did you misspecify an argument? Making 'packages.html' ... done Wrapping the call in suppressWarnings() doesn't stop this, and this warning is printed every time the resultant object is called, e.g. df <- slot(object, name); df, would not print the error on the first call, but would print the warning...

GlobalISel: Ambiguous intrinsic semantics problem
Matt: that’s fair. We’re generally apprehensive of option 2 as well. Eli: Yes, currently we believe that aarch64.neon.addp is the only arm64 one affected, but we don’t know how prevalent this is on other targets. Splitting it is certainly possible combined with the autoupgrader. If disambiguating the intrinsics is the preferred solution, then I think we should also have the langref also specify

[LLVMdev] Language Reference bug?
Hi, The language reference uses "::" many places where it seems it should be using ".. code-block:: llvm". The result is that Sphinx does not colorize these samples. Should I fix this? Or is it purposeful? Also, anybody but me that has noticed that Sphinx does not always colorize things even if you put the proper ".. code-block:: llvm" in front? If it is a known

Survival analysis MLE gives NA or enormous standard errors
Hi, I am trying to fit the following model: sr.reg.s4.nore <- survreg(Surv(age_sym4,sym4), as.factor(lifedxm), data=bip.surv) Where age_sym4 is the age that a subject develops clinical thought problems; sym4 is whether they develop clinical thoughts problems (0 or 1); and lifedxm is mother's diagnosis: BIPOLAR, MAJOR DEPRESSION, or CONTROL. I am interested in whether or not

computationally singular and lack of variance parameters in SEM
Hi all, I am trying to set up a simple path analysis in the SEM package, but I am having some trouble. I keep getting the following error message or something similar with my model, and I'm not sure what I'm doing wrong: Error in solve.default(C) : system is computationally singular: reciprocal condition number = 2.2449e-20 In addition: Warning message: In sem.default(ram = ram, S = S,

ggplot2 - version 0.5.5
ggplot2 =================================== ggplot2 is a plotting system for R, based on the grammar of graphics, which tries to take the good parts of base and lattice graphics and avoid bad parts. It takes care of many of the fiddly details that make plotting a hassle (like drawing legends) as well as providing a powerful model of graphics that makes it easy to produce complex multi-layered

information matrix test in r/s
Greetings, Fellow R-ians: I'm working with a few different quasi-likelihood formulations for some data I'm analyzing. I'd like to implement the Information Matrix Test (see, e.g., White, 1982, or Lancaster, 1984) for each of them to determine which of the models is more likely. Since the null distribution of the test statistic is chi-squared, I envision calculating the ordinate of

question about calling winbugs in R
Dear All: Do you have any experience on calling winbugs in R enviorment? I uploaded R2winbgus, pktools, BRugs, ect. in order to call winbugs. In the end, I try to use bugs(). The error message still displays that bugs() can not find. Do you have any similar issue? If so, could you give your advice? Many Thanks! Xin [[alternative HTML version deleted]]

Major difference in multivariate analyses SPSS and R
Dear colleagues, I know SPSS can not compute linear mixed models. I used 'R' before for computing multivariate analyses. But, I never encountered such a major difference in outcome between SPSS and 'R': In SPSS the Pearson correlation between variable 1 and variable 2 is 31% p<0.001. In SPSS binary logistic regression gives us an Odds Ratio (OR)=4.9 (95% CI 2.7-9.0),

xlsx [path input]
Good morning , i want to read in a file with the xlsx package... the documentation says, that i could define the desired destination with an absolute path. the argument 'file' in the function-call should be: quote : "file->the absolute path to the file which the data are to be read from" (http://cran.r-project.org/web/packages/xlsx/xlsx.pdf ; pagina 14) But it doesn?t work.

Update issue
I have ran rsync once and replicated 25 gigs of data. Now when I run rsync again it goes through all the files again. I thought it was only suppose to get new or changes files. Is there a special switch that I am suppose to use? Thanks SKP

glm throws erroneous(?)'names attribute must be the same length as the vector' (PR#144)
Full_Name: Barnet Wagman Version: 63.2 OS: Linux Submission from: (NULL) (207.229.172.168) After a number of interations, glm(family=binomial) throws an error 'Error: names attribute must be the same length as the vector' The same model works in lm() with the same data frame, so presumably it is not misspecified. In the iterations prior to the error, glm() generates the warnings
