I'm trying to fit the Bass Diffusion Model using the nls function in R but I'm running into a strange problem. The model has either two or three parameters, depending on how it's parameterized, p (coefficient of innovation), q (coefficient of immitation), and sometimes m (maximum market share). Regardless of how I parameterize the model I get an error saying that the step factor has

The problem is badly scaled -- parameters from very small to very big. nlmrt package manages a bit better, but scaling would likely make it and nls both happier. nlxb insists on having its data in a data frame. Here's my code rm(list=ls()) Laptop_sale <- c(1405, 1863,2027,2669,2938,5275,6595,6943,8621,10905,12420,22400,32380,31600,34900,43163,47838,47592) CuSale <- Laptop_sale time

I'm a bass player, I admit it. I came across a number of people talking about bass response with Ogg Vorbis and it piqued my interest, I live for this stuff. I am using the Ogg files to distribute songs as converted right from the 32 bit masters. This is a much different thing than ripping a 16 bit CD audio file that has been mushed and compressed much before it winds up as an Ogg file. When

With Winetricks, Fruity Loops seems to be working well. The only thing that is not working right now is the packs. I can't figure out why the packs aren't working. If I click on the bass pack, it produces sound; if I click on one of the choir packs, no sound is produced. Linux reads the bass pack as pcm encoded. Linux isn't able to read all the packs that aren't working.

I've been trying to run some analysis using the nls function in R but keep coming up with an error message which I don't understand how to fix. The message follows here: Error in nls(formula = f.p, data = n.data, start = list(S = 1, a = -0.1, : singular gradient In addition: Warning messages: 1: In min(x) : no non-missing arguments to min; returning Inf 2: In max(x) : no non-missing

Hi, the anonymous CVS server for portable OpenSSH does not want to talk to me: > % cvs upd -Pd > cvs [update aborted]: connect to bass.directhit.com:2401 failed: Connection refused Looking at http://www.openssh.com/portable.html, ":pserver:cvs at bass.directhit.com:/cvs" is still the recommended repository. Is this a known problem? -- Kent Engstr?m, Link?ping University

I was recently talking to a friend of mine who produces what's widely referred to as "techno", music that's heavy on electronically generated loops and effects, samples, and has plenty of bass. He doesn't like ogg for a few reasons - he sent me a rather long email, and I've stripped out the nonsense from it (he has some technically irrelevant reasons for not liking

Hello I was trying to estimate the weibull model using nls after putting OLS values as the initial inputs to NLS. I tried multiple times but still i m getting the same error of Error in nlsModel(formula, mf, start, wts) : singular gradient matrix at initial parameter estimates. The Program is as below > vel <- c(1,2,3,4,5,6,7,8,9,10,11,12,13,14) > df <- data.frame(conc, vel) >

Hi, I've looked in various FAQs and web pages for this info, but just can't seem to find it. When two tones of two different frequencies sound equally loud, what's the (rough) relationship between their power? This is for percussive sounds in music, but I assume it's roughly the same for all sounds. The ear seems more sensitive at high frequencies. For example, when you

Dear R users,   I am struggling to fit expo-linear equation to my data using "nls" function. I am always getting error message as i highlighted below in yellow color:     ### Theexpo-linear equation which i am interested to fit my data:       response_variable =  (c/r)*log(1+exp(r*(Day-tt))), where "Day" is time-variable   ## my response variable   rl <-

Hi devs :-) At the Mozilla Festival in London recently, I took part in a Hack the DJ workshop, looking at ways to take digital DJ'ing to the next level: http://www.bbc.co.uk/blogs/researchanddevelopment/2011/11/setting-a-dj-challenge-at-the.shtml One of the ideas proposed was stem mixing, using multichannel files in DJ applications. A proprietary implementation of this idea is Fireplayer

Hi, at least for three days now I can't update my sources from CVS. When connecting to the CVS server I'm getting a cvs [update aborted]: connect to bass.directhit.com:2401 failed: Connection refused message. I'd like to make a `cvs diff' since I have an important patch related to a SEGV in the Cygwin sshd. What's the problem with bass.directhit.com? Corinna -- Corinna

Hi, I am a non-expert user of R. I am essaying the fit of two different functions to my data, but I receive two different error messages. I suppose I have two different problems here... But, of which nature? In the first instance I did try with some different starting values for the parameters, but without success. If anyone could suggest a sensible way to proceed to solve these I would be

I am having a problem with two models that each have a HABTM relationship to the other. For example: CREATE TABLE people (id INT, name TEXT); CREATE TABLE teams (id INT, name TEXT); CREATE TABLE people_teams (person_id INT, team_id INT); The person model has: has_and_belongs_to_many :teams And the team model has: has_and_belongs_to_many :people The trouble comes when trying to destroy

Hi, I've been using Speex in my voice-over-IP program on Win32, in wideband (16kHz) mode. I just starting using VBR recently and have run into something that might be a problem within Speex: If someone hasn't spoken for a little while, and the bitrate drops to very low, sometimes the high half of the spectrum becomes frozen with a looping sound. The bottom half of the spectrum is

Hello, Our static analysis tool finds some possible data races in the OCFS2 file system in Linux 6.4.0-rc6. In most calling contexts, the variables such as res->lockname.name and res->owner are accessed with holding the lock res->spinlock. Here is an example: lockres_seq_start() --> Line 539 in dlmdebug.c spin_lock(&res->spinlock); --> Line 574 in dlmdebug.c (Lock

Hi, there. While waiting for the encoder RC1, I will report some minor problems I experienced with Peter's Winamp decoder. First, I am using Nullsoft Vorbis Decoder v.1.11a with Winamp v.2.76 on Windows 98 SE. 1. When the buttons of Playlist Editor are extended, the part extended in playlist screen seems to be flickering when an Ogg file is being played. 2. I check the option of
