Is there any way to identify or infer the inflection points in a smooth spline object? I am doing a comparison of various methods of time-series analysis (polynomial regression, spline smoothing, recursive partitioning) and I am specifically interested in obtaining the julian dates associated with the inflection points inferred by the various models. Tyler e.g.

Hi! Some weeks ago I discovered R. Now, I have a somewhat complicated task and am not sure whether R is the right tool to solve it. I got data of several series or measurements where I have to find the two inflection points. I did a linear regression (with ^2 and ^3 arguments), the problem there was that I had to look only at a very narrow band of measurement in order to get the

Dear all - I have followed the thread the reply to which was lead by Thomas Lumley about using pweibull to generate fitted survival curves for survreg models. http://tolstoy.newcastle.edu.au/R/help/04/11/7766.html Using the lung data set, data(lung) lung.wbs <- survreg( Surv(time, status)~ 1, data=lung, dist='weibull') curve(pweibull(x, scale=exp(coef(lung.wbs)),

Hi R help, I am trying to determine how nls() generates a function based on the self-starting SSlogis and what the formula for the function would be. I've scoured the help site, and other literature to try and figure this out but I still am unsure if I am correct in what I am coming up with. ************************************************************************** dat <-

Hi: I have a problem with the plural of fracancia, I got fragancium but in spanish is fragancia. I modified inflections in environment.rb Inflector.inflections do |i| i.irregular ''fragancia'', ''fragancias'' end but is ignored. The solution that I found was comment this inflection on inflections.rb #inflect.singular(/([ti])a$/i,

Hi, As part of an application I''m developing, I''ve build a translation system (that I hope to release later) fitting my needs. However, I wondered if it would be a good idea to use inflection rules to pluralize translations. Is it possible to have inflection rules for multiple languages in parallel? I need at least french, dutch and english in the same application at the same

Hi, I have this non-linear function: y=115.251 - 118.69 * exp(-0.123517*x) I try to discovery the x value for the assyntoptic value of y and the x value where the behavior of curve change, the inflection point. How to make this? Is poss?ble to make this on R? Thanks Ronaldo -- O Flamengo e o Bangu terminaram o jogo em 0 x 0. Quem fez o gol? A Volkswagen -- | // | \\

Hello! I have a dataset with the following two vectors: year<-c(1967,1968,1969,1970,1971,1972,1973,1974,1975,1976,1977,1978,1979,1980,1981,1982,1983,1984,1985,1986,1987,1988,1989,1990,1991,1992,1993,1994,1995,1996,1997,1998,1999,2000,2001,2002,2003,2004,2005,2006,2007,2008,2009)

Dear All, I have a binomial response with one continuous predictor (d) and one factor (g) (8 levels dummy-coded). glm(resp~d*g, data, family=binomial) Y=b0+b1*X1+b2*X2 ... b7*X7 how can I get the inflection point per group, e.g., P(d)=.5 I would be grateful for any help. Thanks in advance, Ren?

Hi, I am just trying to setup an application in Rails 4, Beta 1. The application is (exclusively) in German Language and therefore also the URLs should be German. I want to create a controller and model for an entity called "Region"; Rails pluralizes that to "Regions", but it should be "Regionen". What I did is: in config/application.rb uncomment this line:

Hi all, I am not used to using the computer to do calculus and have up to now done my differentiation "by hand" , calling on skills I learned many years ago and some standard cheat sheets. My interest at present is in getting the second derivative of a gaussian, which I did by hand and results in a somewhat messy result involving terms in sigma^5 .. I have done some spot checks

I have noticed quite a few changes regarding register allocation. I am wondering will there be support for radically different data structures other than the LiveIntervals, Virtual Register Map, etc? I have build a custom data structure which has it's own intermediate representation like live-intervals, but much more conducive for my allocation algorithm. I do not know if LiveIntervals can

If anything, these data structures are going to be simplified. For instance, VirtRegMap's

Monty, You helped me out quite a bit the other day, but I just wanted to make sure I understand something. The "ideal" way to do bit rate peeling is to have the encoder set the file up to be conducive to the peeling process, and the streamer would be the device that actually does the peeling. Am I correct in assuming, then, that the decoder would think that the file it is

HPA, now that syslinux release madness has calmed down, could you provide some info on how we syslinux-minions/wannabes can use bochs and/or qemu to run (sys|pxe|iso|ext)linux in an emulated environment thats more conducive to debugging, single-stepping, and ultimately understanding how the magic happens ? tia jimc

I'm sure there must be various peak-finding algorithms out there. Not knowing of any, I have written one myself*, but I thought I'd ask to see what's out there. Basically, I have a 2-dimensional data set and I want to identify local peaks in the data, while ignoring "trivial" peaks. My naive algorithm first identifies every peak and valley (point of inflection change

Yesterday, I opened a GitHub Issue<https://github.com/rails/rails/pull/7071> about moving Rails inflections to an initializer. The idea wasn''t received well, understandably, as generating a large initializer with new Rails apps is pretty unappealing. However, the core members seemed open to the discussion of alternatives continuing here. For those of you not in the know,
