Hi, Does anyone know how to code newton's method for finding the roots of polynomial functions? im not sure whether i need to do this manually, or just code something with a loop to stop when it gets to the desired result thanks guys! _________________________________________________________________ Looking to move somewhere new this winter?

Hey guys, i have a relatively simple problem. I need to use netwon's method to find the root of a polynomial, lets say x^3-2x-1 i start off with p <- function(x) x^3-2*x-1 My method, which im sure is very amateur, is to type another function, which is the derivative of p, and after picking an initial value to start off with, i follow the steps of newton's method manually, but i dont

Hey Guys, i have the sample variances for 1000 samples, and i want to fit it to a chi-squared distribution. after making a loop for the simulation initially, i have the following code to compute the variances samples = replicate(n, rnorm(m, 0, 1), simplify=FALSE) variances = sapply(samples, var) summary(variances) can someone please help me fit this to a chi-squared distribution with n degrees

Hey guys, sorry im drawing a mental blank. i have coded the function: y <- function(x) 6*x^4-(1*x^2)^3 How do i evaluate this function for a given x? i know this is a ridiculous question, but thanks anyway _________________________________________________________________ [[elided Hotmail spam]] [[elided Hotmail spam]] =Domain_tagline&_m=EXT [[alternative HTML version

Hi Guys, Im trying to find the exponential of a matrix. Can someone please help me do this?

Hi Guy, I am having trouble graphing the following function √2Γ(n/2)/[√n − 1Γ((n − 1)/2 for the values of n between 2 and 50. i know that Γ(n) = (n-1)!, which in R is factorial(n-1) When i type that into R, using y <- function(n)..... and then plot(y,2,50), it doesnt give me anything meaningful, in fact, it comes up with a message saying something like "in gamma(n+1) ploted" or

Dear R users, Can anyone please tell me how to generate a large number of samples in R, given certain distribution and size. For example, if I want to generate 1000 samples of size n=100, with a N(0,1) distribution, how should I proceed? (Since I dont want to do "rnorm(100,0,1)" in R for 1000 times) Thanks for help Debbie

Hi Guys, i think this is a relatively simple question. I have coded the following polynomial function y= function(x) x^3-2*x^2+1 I need to find the inverse of this, but the code i am using now isnt returning what i want it to. What is the general code for finding an inverse function? Thanks guys _________________________________________________________________ View photos of singles in

Hi, This is the output from queue show 28: 47 (DAHDI/g0/12345678) (realtime) (Ringing) has taken no calls yet Why is the devicestate "Ringing" when no channels is calling this number, and the queue says "has taken no calls yet"? Is it picking up the general state of a random channel on g0 in dahdi? Or what is happening? It only seems to happen with this particular

Hi, I'm having problems with CDR's and Queues in Asterisk 1.6.1. Heres three examples: Normal call: User A calls in to asterisk, gets a PlayFile, and hangs up. This gives 1 CDR as expected. Call to a Queue and then a playfile afterwards: User A calls into asterisk, goes into a queue, asterisk calls user B. When user B hangs up a CDR for User A is generated. (no CDR for user B)

Hi, I have read that DAHDI automagically turns of echo cansellation when it sees that it is a FAX. So I checked this out. I have a fax call into asterisk which is immediately called out to an external fax machine via DAHDI again.. For example, the result is: DAHDI/1-1 = incoming call, DAHDI/2-1 outgoing call. Now, with the help of dahdi show channel, if I check channel 2: echo cancellation is

Hello! We're looking for a solution to reliably load balance our Asterisk boxes. So far we've been using a hodge-podge of directing different services to different boxes/IPs, but eventually I'd like to consolidate things so we can present a single IP address to the outside world. My question is - how do we go about doing that? I've read a lot of things like load-balancing via

Hello 1* I need to use logistic regression. But my data file is very huge( appx. 4 million line). R doesn't handle such a file. What can I do ? ------------------------ 2* So, I thought whether I could perform sta. analyses on summarised data (count of yes/no values) of the huge file. Normally, summarised data file short and R could handle it. Then I used this command. > lo
