Dear R-help readers, I am writing to you in order to ask you a few questions about distribution fitting in R. I am trying to find out whether the set of event interarrival times that I am currently analyzing is distributed with a Gamma or General Pareto distribution. The event arrival granularity is in minutes and interarrival times are in seconds, so the values I have are 0, 60, 120, 180, and

I am just trying to teach myself how to use the mle function in R because it is much better than what is provided in MATLAB. I am following tutorial material from the internet, however, it gives the following errors, does anybody know what is happening to cause such errors, or does anybody know any better tutorial material on this particular subject. >

Dear R users, I have to call fortran program from within R (R 2.8.1 on ubuntu 8.10 machine). Suppose I have a fortran code like this (this is only a toy model, my working model is far more complex, but input/output is similar) DOUBLE PRECISION FUNCTION model(times, alfa, beta) DOUBLE PRECISION alfa, beta, times model=beta*sin(times)+alfa*cos(times) END FUNCTION which

I have a data with 236 observations. After plotting the histogram, I found that it looks like non-central t distribution. I would like to get MLE for mu and df. I found an example to find MLE for gamma distribution from "fitting distributions with R": library(stats4) ## loading package stats4 ll<-function(lambda,alfa) {n<-200 x<-x.gam

Hello everybody! I keep on trying to make my samba installation to work. I have tried a couple threads before but I have not been able to pinpoint the problem. So, yesterday I made a second last attempt to solve the problem before my boss forces me to install Windows2003 since it works out of the box. The scenario is that I'm trying to use Samba (Suse 10) as a fileserver that

Dear all, I appreciate suggestions for following problem. I wrote to RStudio: plot(c(1,20),c(1,20), xlab = expression(paste(alfa))) or the same happen when I wrote: plot(c(1,20),c(1,20), xlab = expression(alfa)) what happen is, that description under x label is exactly "alpha", not greek letter alfa (?). Please where should I search problem, or what information to sent to list for

Hello I?m need fitt growth curve with data length-age. I want to evaluate which is the function that best predicts my data, to do so I compare the Akaikes of different models. I'm now need to evaluate if changing the initial values changes the parameters and which do not allow to estimate the model. To do this I use the function nls(); and I randomize the initial values (real positive number).

Hi, I'm doing a function that describe two populations in competition. that's the function that i wrote: exclusao<-function(n10, n20, k1, k2, alfa, beta, t){ n1<-k1-(alfa*n20) n2<-k2-(beta*n10) if(t==0){plot(t, n10, type='b', xlim=range(c(1:t),c (1:t)), ylim=range(n10, n20), xlab='tempo', ylab='tamanho populacional') points(t, n20, type='b',

Hi all, I would like to install/test CentOS 7.X as a hostap for my home. I am thinking to use an Alfa (http://www.alfa.com.tw) usb wireless adapter or TP-Link. BUt there is not much information in Alfa's or TP-Link's web sites about which of them can run as a HostAP. If I can find any adapter that supports ac with a throughput of 150 Mbps/300Mbps, it would be great. Any recommendation?

Hi everyone, I have dataset which I make a sample of it couple of times and each time I get the mean and standard deviation of each row for each sample. I have a function for that, which takes the name of the file and number of times to sample and then returns the mean and standard deviation for each row in each sample. Sample=function(name, n){

Good morning, I'm looking for a good USB Wifi NIC that will work with the kernel modules for a stock CentOS 8.1. I have an ALFA AWUS036ACH NIC but it looks like the drivers need to compiler for the kernel and I'm having trouble with that. So I'd like something that works, but not necessarily high performing, so I can build the drivers for the ALFA NIC. Thanks! Jeff
