similar to: How to prove the MLE estimators are normal distributed?

Dear List, This problem is more a statistic one than a R one. Any one can recommend me some references website or online paper on maximum likelihood estimation?I'm now working on that,while still doubt how to prove that the estimated parameters are normal distributed. Thanks for your time and help! Best, Ning

Hi, I'm trying to find the maximum (likelihood) of a function. Therefore, I'm trying to minimize the negative likelihood function: # params: vector containing values of mu and sigma # params[1] - mu, params[2]- sigma # dat: matrix of data pairs y_i and s_i # dat[,1] - column of y_i , dat[,2] column of s_i negll <- function(params,dat,constant=0) { for(i in 1:length(dat[,1])) {

[resending, cutting out git pull-request output to make message smaller] Hi all, I have written a COM32 module called "acpioff", that, not surprisingly, powers off a machine using ACPI. I have tested it only using pxelinux.0 with a SeaBIOS/Qemu virtual machine. Since the changeset pulls in a "Linux-ized" version of the open source ACPI Component Architecture, it was too big

Hi, I have Lenovo laptop with an Intel wireless and Bluetooth adapter, running CentOS 6.9. The wireless works just fine, but I can't seem to get Bluetooth to work.

Dear List, I'm now using Ubuntu 10.10 and I want to use the garchoxfit function.It seems that I need to download the package. While after installing the package,I still can't use the garchoxfit function.What's the reason and how to fix that? Thanks for your time! Best, Ning

Good Afternoon, I am relatively new to R and have been trying to figure out how to estimate regression coefficients using the MLE method. Some background: I am trying to examine scenarios in which certain estimators might be preferred to others, starting with MLE. I understand that MLE will (should) produce the same results as Ordinary Least Squares if the assumption of normality holds. That

Dear All, I would like to propose adding the OSL-3.0 license to the list of "standard" licenses bundled with R: Index: share/licenses/license.db =================================================================== --- share/licenses/license.db (revision 66733) +++ share/licenses/license.db (working copy) @@ -317,3 +317,12 @@ URL:

Dear R Users, Here is another probelm/question. I would like to run some panel regressions with R. Therefore I have combined several time periods of data for different individuals in my database. I have already run pooled OLS but I would need to calculate a Fixed Effects Estimator (within estimator). Unfortunately I couldn't find anything like that in the RSearch and I suppose that lme

Hi, professors I??d like to install R-3.3.2 from .tar.gz on my linux system(CentOS 6.4). When installing, R told me that the version of zlib was too old. So, I eager to know which version of zlib did R-3.3.2 software examine at its configure step. How could I check the version of zlib? I will appreciate a lot if you could do me a favour.

The package elfutils-debuginfod-client is needed for even a minimal install, but it is not available on most mirrors. I suspect some are excluding mirroring debuginfo packages with just a *debuginfo* pattern to rsync, where they should do something like *-debuginfo-*.rpm (which should be good for now as I don't see any package with just "debuginfo" in the name, even in Fedora). The

Hi, I am a user of R computer language.Several days ago,I download R-2.1.0.From the help manual,I saw there is a function "mle" to find the maximum likelihood estimators.But when I try to use this function,there is no this function.Could you help me to solve this problem? I am looking forward to your answer. Thank you. Jun Liu

Hi, Tomorrow, Friday Nov 16th, 2007 at 12:30 PM, we'll be exploring a simple, well-commented example of an AGI script for asterisk. I have absolutely nothing against GUI, but if you want to unleash the real power of asterisk, you'll need to get into AGI (or pay someone else to do it). Because asterisk solutions are mostly limited to your imagination (and a hired hand may or may not have

Hi, I'd like to invite all asterisk users to answer two questions on this form: http://food4wine.ning.com/poll 1) What version do you use in production (1.2, 1.4 or both) 2) and what distro(s) It'll just take a second and the results are public and live (link on the page above)

Hi Users, I have daily series of data from 1962 - 2000, with the data for February 29th in leap years excluded, leaving 365 daily values for each year. I wish to convert the daily series to monthly series. How can I do this using the zoo package or any other package? Thanks ZABLONE OWITI GRADUATE STUDENT Nanjing University of Information, Science and Technology College of International

Dear Users, I have a monthly data for a number of years(1960-2007) for a number of stations and i wish to extract sesonal time-series for the months of March-May and October-November for very station. I have read this data with read.table in R with stations as columns and time (months) as rows. My attempt to aggregate with the zoo package using the function as.yearqtr failed since this sums

There has been recent discussion about alternatives to the model-based standard error estimators for lm. While some people like the sandwich estimator and others don't, it is clear that neither estimator dominates the other for any sane loss function. It is also worth noting that the sandwich estimator is the default for t.test(). I think it would be useful for models using other
