...and related quantities (such as residuals). While this is convenient for some kinds of analysis, it negates the space saving effect of compacting the training data into the model parameters. 2. Any function created in the loop contains the training data in its enclosing environment. For example, a linearising transform defined as linearise <- function(x) { x^gamma } (where gamma is derived from the training data) does not only contain `gamma` but other objects in its enclosing environment as well (e.g. intermediate computations in the loop). If `linearise` is returned with the model, those obj...

Hi everyone, I am trying to fit a sine function on one year of wind data. I have two questions below. Looking around on the net I managed to get the following: Sine Equation: y = a + b * sin( c + d*x ) b is the amplitude, c is the phase shift, d is something deal with periodicty of data*.* This can be linearised by sin( c+dx ) = cos(c) * sin(dx) + sin(c) * cos(dx). If one calls dx = x1 y

Hi dear R-helpers, Happy new year. I have estimated Gini index variance in the case of complex survey (stratify and with two stage sampling). I use the survey package. I use replication (bootstrap, and Jacknife) and linearisation according to Binder (1993) article David A. Binder and Milorad Kovaˇcevi´c(1993), « Estimating some measures of income inequality from survey data : An

Dear all, I sent an email on Friday asking about nlrq {quantreg}, but I haven't received any answer. I need to estimate the quantile regression estimators of a model as: y = exp(b0+x'b1+u). The model is nonlinear in parameters, although I can linearise it by using log.When I write: fitnl <- nlrq(y ~ exp(x), tau=0.5) I have the following error: Error in match.call(func, call = cll) :

Dear list members, this is not an R question and forgive me for using the list for irrelevant questions, but this is the only place I know where I can find some good statisticians and I need an expert opinion. There is this power law kinetic model of the form: M=kt^n where t is the time, M is the fraction of drug released, k is the rate constant and n is an exponent related to the mechanism of

I actually posted about this here on samba list about it last year, but nobody caught interest. I used to have logs from samba and wireshark, which very nicely showed what's wrong (kerberos request was for SPN  eg. "Hyper-V Replication Service/Servername.mydomain.com" and in samba log there was an error with something like "Hyper-V\ Replication \Service.. not found".

Hi: I have usually used the GROWTH() excel function to do this but now want to see if I can do this with R. I want to predict values into the future, possibly with the predict.arima Function. I have the following weekly fish weight averages: weight <- c("2.1","2.4","2.8","3.6","4.1","5.2","6.3") week <-

Dear all Please, can you advice me how to compute an error, standard deviation or another measure of variability of computed value. I would like to do something like: var(y) = some.function(var(x1),var(x2),var(x3)) for level F1 (2,3,...) Let say I have some variables - x1, x2, x3 (two computed for levels of factor F and one which is same for all levels) and I want to compute y =

I have a suspicion that it is related to the specific SPNs that hyperv uses. Hyper-v tries to register 3 spn (typing from memory so I might be a bit off): Microsoft hyper-v console/HOST.FQDN Hyper-V Replication Servive/HOST.FQDN Microsoft Hyper-V Live Migration Service/HOST.FQDN. This fails because of the spaces, that is samba being on linux, not seeing escape characters, messes up the request it

This is almost ideal for SLP vectorization, except for two problems: 1. We have 4 stores to consecutive locations, but the last element is the constant zero, and not an additional SUB. At the moment we don’t have support for idempotence operations, but this is something that we should add. 2. The values that we are subtracting come from 3 loads. We usually load 4 elements from memory, or

Hi, I am trying to fit a model with an ordered response variable (3 levels) and 13 predictor variables. The sample has complex survey design and I've used 'svydesign' command from the survey package to specify the sampling design. After reading the manual of 'svyglm' command, I've found that you can fit a logistic regression (binary response variable) by specifying the

I just discovered the great piece of software that is available with the survey package. Many thanks and 'Hats off' to Thomas Lumley. While package survey covers analysis of features of objects sampled (in clusters, strata) I could not find analysis of features of repeated relationsships between sampled objects (in clusters, strata). My understanding is that it is not adequate to treat

Hi, This probably isn't significant evidence about using svn as the authoritative revision control system for llvm but more just to point out that the svn users tend to consider that the only thing one would use revision control for is the mainstream development history tracking. I'll note that I during working ("development" but also bug-fixing and experimentation) since the

Hi Hal, you are right. Preston's dependence-analysis and Polly are sharing the same problem. As far as I know, non of us implemented a solution yet. Preston, what is your status on multi-dim arrays?

Dear all, I have a serious problem to solve my model. I study over exploitation of fish in the bay of biscay (france). I know only the level of catch and the fishing effort (see data below) by year. My model is composed by the following equations: * the growth function Gt(St) = r*St*(1-St/sbar) with Gt the growth of each period t r intrinsec growth of the stock sbar carriyng capacity of the

...just because we don't like it :) One of the observable effects of the program is the last values written into A, and unroll-and-jam will reorder the stores if it does not understand it is unsafe, leading to different output. i.e a mis-compile. C isn't very friendly to us here, and llvm is linearising the access. Some other languages have stronger guarantees about their array dimensions accesses being in range. But this being a flat C array, there is nothing out-of-bounds going on. I'm not sure about just disabling the checks, at least without some other way of keeping the results correct....

The thing about this is that git-svn (un?)fortunately works so well that you can get all of these benefits with the main repo still in SVN. Hence, it is really a moot point regarding a switch to git for the main repo. E.g.: > Actually that's true today with svn. We have a ton of changes here we'd > like to submit but the process is really painful. Is there any difference from the
