Hello R help list, I am using the mda package and in particular the fda routine to classify a set of 4409 trips. I preformed a flexible discriminant analysis (FDA) using a set of 148 trips. A total of 36 predictors were considered. the resulting FDA rule was applied to the 4409 trips and for the same predictors in order to predict to which group the trip will belong. A consistent error is

Hi everybody: I?m trying to rewrite some routines originally written for SAS?s PROC NLMIXED into LME4's glmer. These examples came from a paper by Nelson et al. (Use of the Probability Integral Transformation to Fit Nonlinear Mixed-Models with Nonnormal Random Effects - 2006). Firstly the authors fit a Poisson model with canonical link and a single normal random effect bi ~ N(0;Sigma^2).The

Hello, I am using the mda package and in particular the fda routine to classify/predict in terms of color to a set of 20 samples for which i don?t know the color. I preformed a flexible discriminant analysis (FDA) using a set of 147 samples for which i know all the information. My script and data follow in attachment. A total of 23 predictors were considered. 20 of the predictors are

Hello, I'm trying to do some differential equation modeling in R using the package 'deSolve.' Briefly, I'm trying to use the law of mass action (the details of which aren't really important) to structure a vector of rate equation which will be passed into an ODE function and solved with associated functions from 'deSolve.' Roughly what this entails is scanning

Hello, My name is Maria, MBA student in Sanfransisco, USA. In my credit scoring class, I have hard time making "transition matrix", which explains probability especially in relation to "Markov chain model". It is regarding people's monthly credit payment behavior. Does R have function to caculate it? I am actually a novice in using 'R'. Please help me!!! Maria

Hi, I'm struggling trying to specify a multinomial logit discrete choice model in R. Any help and/or code examples appreciated. I am specifically interested in specifying a model where no universal choice set exists and each choice set has a variable number of alternatives (one of which is chosen) see data below. Many Thanks, David PS I have asked earlier but without reply. Is it

I am trying to learn something of the algorithms used in Vorbis. One of them is the "Modified Discrete Cosine Transform" (MDCT). I have found a couple of books with brief descriptions of the DCT, but almost nothing about MDCT. (1) is there just one Modified DCT, which can be expected to be the same whenever someone uses that name, or does it just mean that you have changed

Hi I am trying to estimate stated preferences for Tv sets by using mlogit. The choice set is designed as with 4 attributes: [ brand(has 4 levels), technology(has two levels), class[has 4 levels), price(has 4 levels)] There are 16 choice sets with 4 alternatives each one (i.e. each respondent has evaluated 64 cards in total). Therefore, there are 64 rows in the table below. The data in csv file

I only concern about the boundary of the shape and I don¡¯t concern gray level. U[m] = x[m] + jy[m] m= 0,1,¡­,N-1 is the N points on the boundary. It is easy to express U as a discrete Fourier series. But it seems like that wd in the wavethresh package cannot deal with complex values. And it is not interesting to transfer U to a matrix. Thanks a lot Qin

Dear all, I haven?t used R for panel data analysis so far, but now I am looking for a package respectively some starting point for binary choice panel data analysis in R. For starters most of my effects are individual and my dependent variable is just binary. Thanks for any suggestions in advance! best matt

To all, Does anyone know whether there are any Discrete Choice Modeling modules for R?? Thanks, Charlie ------------------------- Charles H.

Hello list: I generate by simulation (using different procedures) two sample vectors of size N, each corresponding to a discrete variable and I want to text if these samples can be considered as having the same probability distribution (which is unknown). What is the best test for that? I've read that Kolmogorov-Smirnov and Anderson-Darling tests are restricted to continuous data

I'm reading a old statistics book "MARVIN J. Karson (1982), Multivariate Statistical Methods, The IOWA State University Press, Iowa". In the chapter XI i can find some information about discrete multivariate analysis. This chapter is restricted to an introduction to log-linear models for analysis of multidimensional contingency tables. For example, in the log-linear model for

Hey I want to generate a discrete uniform distribution as follows: For example: I want to get 278734 records each with a numbers between 7-10. And the sum of numbers in 278734 records to be equal to 2253712. Once this is done, I want to get that printed to an excel file such that Record Value 1 9 2 7 so on 278734 8 The

Hi everyone, We have been trying to construct a Lasso-cox model with discrete time. We conducted follow-up examinations on the epileptic attack after tumor surgical resection among glioma patients. The patients are followed-up in the 6/12/24 months after surgical resection, which makes the epilepsy-free time discrete (6/12/24 months). We calcluated many features from the T2-images

The "tscount" package (see http://doi.org/10.18637/jss.v082.i05) comes with several count data time series.

Hi r-help, I have been using your RHmm package for some time and have recently had to try using the package for a new dataset. Basically I have a dataset with a number of discrete observation variables that change over time, and I would love to try modeling them using a HMM. Basically I was wondering if RHmm can be used to model a multivariate discrete HMM, i.e., the observations are a vector
