How can I plot each person's trajectory in the *same* panel, along with the mean-level trajectory?

permutation test assumption?
Dear all, Can I do a permutation test if the number of individuals in one group is much bigger than in the other group? I searched the literature but I didin´t find any assumption that refers to this subject for permutation tests.

Need to replicate Boltzman Signmodial Curve fit from Graph Pad
Hello useRs (please don't kill me), I've fairly new to R having only a few months of playing around with R. What little I've learned has been extremely useful. If someone could point me as to how to replicate the Boltzman Sigmodial curve fit as provided by Graphpad software I'd be eternally grateful. Where we currently use Graphpad for only this one function,its seems highly

extended Kalman filter for survival data
If you mean this paper by Fahrmeir: http://biomet.oxfordjournals.org/cgi/content/abstract/81/2/317 I would recommend BayesX: http://www.stat.uni-muenchen.de/~bayesx/. BayesX interfaces with R and estimates discrete (and continuous) time survival data with penalized regression methods. If you are looking for a bona fide Bayesian survival analysis method and do n...

FlexMix for clustering of gene expression data
Hello, I'm trying to cluster gene expression data as in http://bioinformatics.oxfordjournals.org/content/28/2/222.full It looks like they are using some combination of FlexMix and mgcv but I haven't been able to figure out the exact steps necessary to perform the clustering. Has anyone else used FlexMix to do clustering on this type of data before? Any pointers would be much apprecia...

confirming a formula for use with lmer
Hello, I recently began using R and the lme4 package to carry out linear mixed effects analyses. I am interested in the effects of variables 'prime','time', and 'mood' on 'reaction_time' while taking into account the random effect 'subjects.' I've read through documentation on lme4 and came up with the following formula for use with lmer:

Discrimination of almost-random time series
Dear time-series specialist: I've got some time series representing measurements from a physical process, like atomic decay data. These time series look almost random, but should hopefully be distinguishable as they were taken under different conditions. I am looking for statistical approaches that are sensitive enough to discriminate between such series of measurements. Preferably, there

"cophenetic" function for objects of class "dendrogram"
Note that cophenetic.default (which works on the output of hclust(dist(X))) uses the row names of X as labels. as.dendrogram.hclust does not retain those row names so cophenetic.dendrogram cannot use them (so it orders them based on the topology of the dendrogram).
