Dear All,   I am working on a time series of hourly river flow measurements from 2000 - 2003  and have been trying to compute the extremum index from the original series as well as a new series from  sampling with replacement . The extremum Index produced from the original data series looks  fine but sadly, a strange value of index is given from the sampling. The flow measurements are in range of

Greetings, R-Wizards: I'm trying to find an extremum subject to a nonlinear constraint. (Yes, I have perused the archives but have found nothing positive.) The details of the problem are these: In a paper published some years ago in Technometrics, ("Confidence bands for cumulative distribution functions of continuous random variables" Technometrics, 25, 77-86. 1983), Cheng and

Dear Niharika, As I said before, the problem is basically an optimization issue. You should isolate the problematic part from the rest of your study. Sometimes, more information does not help to solution. All the answers from us (Ulrik, David, me) are more or less are correct to find a maximum point. Newton?s method is also correct. But after answers, you only say, it didn?t find the right

I have not followed the history of this thread, but I am quite flummoxed as to why the OP is rewriting code to estimate parameters from an univariate Gaussian mixture model when alternatives such as EMCluster (which generally appears to handle initialization better than MClust) exist. Or perhaps there is more to it in which case I apologize. But I thought that I would make the OP aware of the

I have a problem where I have two columns of data that I can simply plot using: plot(wV[0:15,3],wY[0:15,3]). This produces my desired plot. Now, say I have a third variable that I would like to introduce and use that variable to set different colors in the plot In this case, say I wanted values greater than 0 to be "blue" and values less than 0 to be "red" Basically, my

Hi, I am trying to assemble a three-way contingency table examining the presence/absence of mussels, water depth (Depth1 and Depth 2) and water velocity (Flow vs. No Flow). I have written the following code listed below; however, when run the glm I get the following message, "Error in model.frame.default(formula = Count ~ MP + wd + wv, drop.unused.levels = TRUE) : variable lengths differ

Hi all, Assume the following function that generate a random number. z1<-function (n, eta) { wv <- runif(n) wz <- (-1/eta) * log(wv) wz } y <- z1(100,4) mean(y) I want to run this function say 1000 times and I want to count if the mean(y) outside the following range 0.20 to 0.30. How do I do it in R? Thanks in advance

Hi I work for a medium sized University and have recently set up some new infrastructure to authenticate our wireless users of Active Directory. Every thing was working as expected or so I thought. I set up a monitoring script that performs an ntlm_auth every minute and it shows that the authentication is failing inconsistently but for around 5 minutes at a time (see below). There are two

Hi, I'm trying to make a regression of the form : formula <- y ~ Asym_inf + Asym_sup * ( (1 / (1 + (n1 * (exp( (tmid1-x) / scal1) )^(1/n1) ) ) ) - (1 / (1 + (n2 * (exp( (tmid2-x) / scal2) )^(1/n2) ) ) ) ) which is a sum of the generalized logistic model proposed by richards. with data such as these: x <- c(88,113,128,143,157,172,184,198,210,226,240,249,263,284,302,340) y <-

Dear R-Users, I need to find a smooth function f() and coefficients a_i that give the best fit to y ~ a_0 + a_1*f(x_1) + a_2*f(x_2) Note that it is the same non-linear transformation f() that is applied to both x_1 and x_2. So my first question is how can I do it in R? A more general question is this: suppose I have a utility function U(a_i, f()), where f() is say a spline. Is there a general

I know this unnecessary lookups question is really a postfix one, but I'm curious if anyone else sees the behaviour of postfix continuing looking up users after it clearly have got its answer that it is "not a local domain" response.

Tom, this may be good for embedding small data sets, but for practical purposes is doesn't seem like the most efficient solution. Since you didn't provide any code, I built a test case using the build-in Java JSON API to build a medium-sized dataset (1e6 rows) and read it in just to get a ballpark (see https://gist.github.com/s-u/4efb284e3c15c6a2db16 # generate: time java -cp

Hi Folks, If you need to send data from Java to R you may consider using the JDataFrame API -- which is used to convert data into JSON which then can be converted into a data frame in R. Here's the project page: https://coherentlogic.com/middleware-development/jdataframe/ and here's a partial example which demonstrates what the API looks like: String result = new JDataFrameBuilder()

Anyone got a preferred program or package for this? I'd like a *good* one, and Word or OO.o's save as html in no way qualifies as other than amateur crap. So far, with a little googling, I've found the wv package. wvHtml works, but I don't like the output - it insists on <div>, and on &rhquo instead of plain, simple ". mark "what, ask for an opinion in

The problem I was experiencing is still occurring, and it is getting worse. There are several names that Festival "gets stuck on". I don't know if it is a Festival problem or an Asterisk problem. The scenario, a call comes in goes through the dialplan (shown below in original message), and either reads the value ${FULLNAME}, but then hangs. It doesn't go to the next command
