similar to: two term exponential model

Hi all, I have a dataset which consists of 2 columns. I'd like to plot them on a x-y scatter plot and fit an exponential trendline. I'd like R to determine the equation for the trendline and display it on the graph. Since I am new to R (and statistics), any advice on how to achieve this will be greatly appreciated. Many thanks, Chris -- View this message in context:

Hi, I am trying to fit experimental points by exponemtial curve my data are stored into a matrix data the first column is the geographical point (a number = data[,1] ) ( I would like to plot several graphes at the same time) the second column is the time of measurement (x in the plot) the third column is a speed (y in the plot) if we assume the point are folowing this exponential behaviour

Hi, I want to fit some psychophysical data with cumulative gaussians. There is quite a convenient toolbox for matlab called 'psignifit' (formerly known as 'psychofit'). It allows the lower bound of the sigmoid to vary slightly from zero, aswell as the upper bound to vary from one. with these two free parameters, the fitted function is less sensitive to noisy data and outliers.

Hi all. Has anyone ever done a Deming Regression in R? I'm wondering if there's a simple way to do it. Thanks for all your help! -Ed -- View this message in context: http://www.nabble.com/Deming-Regression-tp17949318p17949318.html Sent from the R help mailing list archive at Nabble.com.

I am trying to clear up all the "NOTE"s before a CRAN submission, but am a bit confused about this one.?? What is it complaining about -- that it doesn't like my name? ... * checking for file ?deming/DESCRIPTION? ... OK * this is package ?deming? version ?1.4-1? * checking CRAN incoming feasibility ...

Hi, I'm attending summer School at UCLA (IPAM) on "probabilistics models of cognition". I have been an R-user since v. 1.4.1, but was trained in the frequentist tradition (as most psychologists!). I found that all faculty here use matlab and Murphy's bayes net toolbox. I have not had the need to use matlab before, and would love to stick to R for graphics models and

I have a Windows application that I would like to have running on Linux as it is my platform of choice. This application is a proprietary Visual Basic program. It's name is crisscross real-estate. Using the latest codeweavers-wine I was able to install it on a pre-install windows directory layout and the application is behaving very well except that in at one point in the program I get an

There are a couple of points to keep in mind when doing a log-transform of an exponential model, such as -- y = a*exp(b*x) 1. The implicit statistical model is multiplicative in the error. The implied statistical model of the log transform is -- log(y) = log(a) + b*x + u which implies -- y = a*exp(b*x)*exp(u) A linear regression in the log

I've got an rsync job which is consistently failing, but I've been unable to diagnose the problem. FAQ/Google/docs/etc. checked and no luck. Basically, it looks like the rsync process invoked on the far end is exiting, and then the local process waits until the timeout and exits. Both systems are Sun boxes, Ultra 10 or better with 256+ MB of memory. Rsync version is 2.5.0 on the local

Dear all! Although the Psycho-Toolbox for Matlab is free software, Matlab isn't. I'm planning to do an experiment where it's essentail to travel to the subjects, not let the subjects come to where the Matlab licences are :-( So I need to use a free software for my experiment if I don't want to by an extra Matlab licence (which I don't want to). Did anyone ever try to do

Is there any R package that implements the same capability of MatLab toolbox called SimBiology ? We are expecially interested in protein-protein interactions and network analysis. As far as I know SimBiology implements a system of ODEs reflecting the kinetic chemical reactions. We would be more interested in stochastic simulations. Thank you in advance.

Dear R users, I have a question about the patterned variance-covariance structure for the random effects in linear mixed effect model. I am reading section 4.2.2 of "Mixed-Effects Models in S and S-Plus" by Jose Pinheiro and Douglas Bates. There is an example of defining a compound symmetry variance-covariance structure for the random effects in a split-plot experiment on varieties of

Hi! I'm translating some code from Matlab to R and I found a problem. I need to translate Matlab's function 'lsqnonlin' (http://www-ccs.ucsd.edu/matlab/toolbox/optim/lsqnonlin.html) into R, and at the beginning I thought it would be the same as R's 'optim'. But then I looked at the definition of 'lsqnonlin' and I don't quite see how to make

Dear Sir or Madam: Dose anyone know the R function which corresponds to "fcdf", a "F cumulative distribution function" of Matlab? http://esra.univ-paris1.fr/matlab5/toolbox/stats/fcdf.html Please guide me how to get this function if it is available. ..... or code it ab initio if no function in R language Thanks for kind reply further.

Hi, I have a dataset which has var1 from 1 sourse and var2 from 2 different methods. I need a new variable such that var2 values from both methods can beused as 1 variable. I believe deming regression can be used to do this. I just don't know how to do it. My data looks like: idvar1var2method1var2method2 11.22.1NA 21.62.4NA 31.52.2NA 41.3NA2.8 51.6NA3.1 61.4NA2.7 Please help. Sincerely,
