similar to: Non-Markovian Behaviour of a Cusum?

I wonder if someone can help me understand some counterintuitive simulation results. Below please find 12 lines of R code that theoretically, to the best of my understanding, should produce essentially a flat line with no discernable pattern. Instead, I see an initial dramatic drop followed by a slow rise to an asymptote. The simulation computes the mean of 20,000 simulated trajectories

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,

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

I need to write a C# program to create and display Cusum chart from any of the packages, spc, qcc or strucchange. Issues: 1-The data resides in a MS SQL Database. The C# program will handle obtaining the data for the requisite types of samples. Assistance needed on: 1-How can I call the cusum capabilities of any of the above packages and pass the data to the cusum function and plot? 2-How

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?

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

Sorry if this is a naive question, but I only started using R last week. I would like to fit a distribution to data which includes a cumulative sum: P(r) = \sum^{V}_{i=r} D e^{-n/i} i^{-d} This equation is used to fit rank-frequency data: P(r) is the frequency of an entity with rank r; V is the number of unique entity types; and D, n and d are constants to be estimated. I've found out how

I am testing Solr FTS on dovecot. Read online that some suggested to run cronjob commit every minute, and optimize once a day. I am using Solr 7.1.0 and I see some configurations: In /etc/default/solr.in.sh: #SOLR_OPTS="$SOLR_OPTS -Dsolr.autoSoftCommit.maxTime=3000" #SOLR_OPTS="$SOLR_OPTS -Dsolr.autoCommit.maxTime=60000" Also in solrconfig.xml: ??? <autoCommit>

It's a bug in summary.aareg which no one found until now. What's wrong: If dfbeta=TRUE then there is a second estimate of variance calculated, labeled as test.var2. If maxtime is set, then both estimates of variance need to be recalculated by the summary routine. An incorrect if-then-else flow led it to look for test.var2 when it wasn't relevant. My test cases with maxtime also

Hi all, I've ventured into the world of nonparametric survival and I would like to use the "maxtime" option for printing and plotting my aareg fit. However, my fit does not have "test.var2" and this stops the print and plot when adding a maxtime. My code is as follows: Response<-Surv(Time,Event) Model<-aareg(Response~Factor1*Factor2)

I would appreciate any ideas of what I'm doing wrong on this. My dialplan calls an AGI which records a file. That works, but I'm trying to find a way to determine whether the caller pressed # to stop a recording before the maxtime expired, or if the recording ended due to reaching the max timeout. The $fx variable in the below agi excerpt always returns 0. $res =

Hola Daniel, si perdona di a responder directamente y no me di cuenta. Ya se donde esta el error, pero queria preguntar si a puede ser que mi R funcione mal o algo porque esta manhana ejecute mi script y funciono perfectamente y ahora volvi a ejecutarlo y me volvio a dar el mismo problema de ayer , despues de reiniciar y demas el tinnR y el R, no se si me vacila o es que tengo algo mal en

Hola a todos, Me gustaria pedir vuestra ayuda a encontrar el error que no consigo encontrar en este archivo.

You have quite a few mistakes in your example. The code below works for me - you can wrap it in a function if you like. I think you will need a lot more practice before you can write something like this in R as you are missing close braces and haven't really worked out the difference between the number of calculations you are doing for each replication and the number of replications. It takes
