Hello. I have a script in which I repeatedly fit a nonlinear regression to a series of data sets using nls and the port algorithm from within a loop. The general structure of the loop is: for(i in 1:n){ … extract relevant vectors of dependent and independent variables … … estimate starting values for Amax and Q.LCP…

Hello, I have come across a result that I cannot explain, and am hoping that someone else can provide an answer. A student fitted a mixed model using the lme function: out<- lme(fixed=Y~A+B+A:B, random=~1|Site). Y is a continuous variable while A and B are factors. The data set is balanced with the same number of observations in each combination of A and B. There are two hierarchical

Earlier, I posted the following question: I want to superimpose histograms from three populations onto the same graph, changing the shading of the bars for each population. After consulting the help files and the archives I cannot find out how to do this (seemly) simple graph. To be clear, I want - a single x axis (from -3 to 18) - three groups of bars forming the histograms of each population

Hi all, I have some problems inserting data into a legacy table. the key field of this table is a field named CIN which is a varchar(15). when I try insert into this table using a form (generated by the scaffold generator) I get this Error : _____________________________________________________________________ undefined method `CIN_before_type_cast'' for #<Candidat:0x370d8c8> |

I had a look on the website, but I can?t see a detailed list of supported units. The model number is BX700UI.

The server we are using is headless, I can?t install a desktop software unfortunately. That?s why I am trying to find a driver for NUT on OpenMediaVault.

I am analyzing particulate matter data (PM10) on a small data set (147 observations). I fitted a semi-parametric model and am worried about overfitting. How can one check for model fit in GAM? Jean G. Orelien

I am new to R. I'm using the function GAM and wanted to get standard errors and p-values for the parametric terms (I fitted a semi-parametric models). Using the function anova() on the object from GAM, I only get p-values for the nonparametric terms. Does anyone know if and how to get standard errors for the parametric terms? Thanks. Jean G. Orelien

Hi Roger, Thank you for your advise. I tried driver = apcupsd port = auto But unfortunately I get the same error message ?Failed to execute command ?upsc 'ups' 2>&1': Error: Driver not connected" As I am not very good in using OMV, maybe there is something else I should do? Thanks Best regards mikael festa The Studio, Cornfields, Portsmouth Road, Ripley, Surrey GU23

Dear all, I'm trying to compare two sets of variables, the first set is composed exclusively of numerical variables and the second regroups factors and numerical variables. I can't use a Manova because of this inclusion of numerical variables in the second set. The solution should be to perform a Mancova, but I didn't find any package that allow this type of test. I've already

Hi, I am a Ph.D. student from Québec, Canada. I’m a beginner with R and Bioconductor. Until now the only experience I have is in analyzing microarray data using affy and limma packages. Now I am trying to analyze Rat Gene 10 st arrays and I would like to run RMA analysis and Smyth moderated t test on those arrays. Since no cdf official package is available for those arrays, after reading many

I fitted a GAM model with Poisson distribution to a data with about 200 observations. I noticed that the plot of the residuals versus fitted values show a trend. Residuals tend to be lower for higher fitted values. Because, I'm dealing with count data, I'm thinking that this might be due to overdispersion. Is there a way to account for overdispersion in any of the packages MGCV or GAM?

I just upgraded to .22.3 from .22.1 and now i got several error messages. I havent found why i got them.

Dear all, I did a RDA and when I looked to the signification of the test with permutest, the output was non-significant. But when I used the envfit function, some of the vectors are significant. All the test's conditions are respected. What it means? Is it an error in the script? Commands and output: > permutest(rda.ind, perm=999, first=TRUE) Permutation test for rda  Call:

Hello and happy new year :) I have to set up a samba server as a PDC with a openldap backend. My openldap server is fully functionnal and it is not secured yet (so no problems with tls).

Hi, I have upgraded my Dell C151 to the latest 5.6. I have always used ntp to sync this machine and then the rest of the machines in the network would sync from it. Since the update I cannot keep the right time on the machine. This is with / without ntp. I have attempted various scenario's with no luck. I am now trying the old kernel now as I type this out. If anyone else has any
