similar to: Need Advice with C# Program to Create and Display Cusum Chart

I am new to using R and would appreciate some advice on which books to start with to get up to speed on using R. My Background: 1-C# programmer. 2-Programmed directly using IMSL (Now Visual Numerics). 3- Used in past SPSS and Statistica. I put together a list but would like to pick the "best of" and avoid redundancy. Any suggestions on these books would be helpful (i.e. too much

Dear friends: I have just read an article entitled " Monitoring of nosocomial invasive aspergillosis and early evidence of an outbreak using cumulative sum tests (CUSUM)", which is published in "Clinical Microbiology and Infection". We have great need to estimate the fluctuation of incidence of IFI in our hospital. But I don't know the details of the stastical method and

Dear all, Does anyone know where there is R or S code for the CUSUM SQUARED structural breaks approach? (Brown, Durban and Evans, 1975 - used in Pesaran and Timmerman, 2002) The problem is that the breaks package only appears to offer the standard 'unsquared' CUSUM, even though it appears most think it is inferior to the squared version. It might appear to be a relatively simple

Dear R Community: I am working on a public health early warning system, and I see that the qcc package allows for CUSUM and other statistical quality tests but I am not sure if my project is a good match for qcc functions as written. Any advice you may have is very much appreciated. I have four years worth of daily counts of emergency room admissions for different conditions (e.g. respiratory,

Hello R users: I'm trying now to apply the package strucchange to see whether there is a structural change in linear regression. I have noted the following problem that arises in my case with recursive-based CUSUM: generic function recresid() in efp() generates an error, since (probably) it cannot compute the inverse matrix of (X^(i-1)^T)*(X^(i-1)) at each step (i-1), because the matrix

Dear R-help list members, I have the following question concerning the strucchange()-package: is it possible to get the boundaries for one-sided (upper / lower) CUSUM and MOSUM tests? Thank you in advance. Julia

Can anyone advise me on some pratical papers or books On Gaussian Copulas? Anything in the genre of Copulas Dummies Would be a help. As simpe, and approachable with minimal pedantic style.

Hello, I am looking for some help with this question: how could I test structural breaks in a instrumental variables´s model? For example, I was trying to do something with my model with three time series. tax_ivreg <- ivreg(l_y ~ l_x2 + l_x1+ dl_y | lag(l_x2, -1)+lag(l_x2, -2)+ lag(l_x1, -1)+lag(l_x1, -2)+lag(l_y, -1)+lag(l_y, -2), data=tax1) summary(tax_ivreg) ## after estimating it,

Good Afternoon, I am currently writing a program to perform a cusum with v-mask and since I am experiencing a few problems, was wondering if there is something similar in existance?

I have done a cluster analysis doing: 1-clusNorth <-hclust(dist(Artorious)^2, method="ward") 2-clusNorth$labels <-Artorious$Name ## to show the case names and not numbers 3-dend1 <- as.dendrogram(clusNorth) 4-plot(dend1) My Dendrogram is now showing the names of my cases in the dataframe on the x axis 1 OMNICELL INC COM 2 GETTY IMAGES INC

I want to apply Nyblom-Hansen test with the strucchange package, but I don't know how is the correct way and what is the difference between the following two approaches (leeding to different results): data("longley") # 1. Approach: sctest(Employed ~ Year + GNP.deflator + GNP + Armed.Forces, data = longley, type = "Nyblom-Hansen") #results in: # Score-based CUSUM

Hello, we want to identify breakpoints (different phases) in environmental data, algae cell counts of three years with intervals between 7 and 30 days (N=40). We found that breakpoints(cells ~1) works great and identifies 5 very good breaks, however we are uncertain about these, because the data are unequally spaced. Is there a way to include the information about the measurement intervals,

Can anyone please tell whether there is any R function to act as "VEC" and "VECH" operator on Matrix? Yes of course, I can write a user-defined-function for that or else, I can put dim(mat) <- NULL. However I am looking for some R function. Your help will be highly appreciated. Regards, -- View this message in context:

Hi everybody, I am fresh for speex and vs.net c#,and I want to use speex in a existed project written by c# language,does anybody done this before?because I do not know how to use c in c#,I worked under linux environment for years,never touched vc.net.Maybe compile the source code into dll file and use them?I heard about the wrapper,what does this mean, Regards Chris -------------- next part

Hola, Vaya, en el código que he enviado, cusum no se incrementaba.. Y has indicado que se introduce un año más, con el mismo ID que el anterior y con la misma cantidad acumulada. Pero si el siguiente año es del mismo ID, acumula el valor de la cantidad que hemos introducido en esa fila... Con el siguiente código se resuelve este error y además ya está preparado para contemplar cualquier tipo de

Llego tarde al hilo, pero creo que se llega rápidamente al resultado con la complicidad del paquete "reshape2". Si DT es el data.table que escojo Francisco como ejemplo: > DT ID YEAR CANTIDAD 1: 100 2005 1 2: 100 2005 2 3: 100 2007 1 4: 100 2007 1 5: 100 2007 1 6: 120 2006 1 7: 120 2006 5 8: 120 2006 1 9: 120 2007 3

Hola a todos. Se me está plantendo la posibilidad de empezar a aprender C# para hacer algunos programillas (nada grande). El tema es que el otro día en un mail de esta misma lista alguien (lo siento, no recuerdo quien) puso un link a un post en el que se hablaba de la integración entre R y C#. Por supuesto para llegar a poder hacer esto primero tengo que entender las bases de .NET y C#, pero me

Hello, I am trying to conduct a time series analysis on historic hydrologic data, but I cannot coerce it into class ts because it does not have regular sampling intervals (some years have 20 samples, other have 8). Specifically I am trying to perform a CUSUM or or other step change detection, but the packages all seem to require data as ts. Is there a way to coerce my data into ts while

You could compile Speex as a DLL (see libspeex_dynamic.dsp) and use PInvoke. http://en.wikipedia.org/wiki/PInvoke Note that Speex will still be executing as unmanaged code and your program will have the added dependency of the native Speex DLL. It appears that someone created a "Speex.NET" based on JSpeex, but I didn't find any useful info on it. You may want to search for this
