excluding factors from sampling
Hello, I am trying to write a function that first requires randomly sampling items from a set of factors. I need to be able to sample from that same set of factors, but exclude the ones that have already been sampled previously. For example, suppose I have a set of items a-j (a,b,c,d,e,f,g,h,i, and j) and randomly sample a, c, and f from that group. How do I sample again from the larger group

zero inflated poisson and censored-continuous models
I wonder if there is a package that will estimate a Zero Inflated Poisson Model (ZIP), and also if there is a package that will estimate what is called the Tobit model: that is a combination of censored and observed values in the same sample.

nice idea
some times ago i was playing with coding, shannon theoremes and other stuff, i have tried without success to compress audio wave, and i have notice that simply oversampling audio material enacnhe a lot compression ratio i only take awav file, oversampled it by 20 tiimes and then compressi it using pkzip or rar. i don0't remember if i also do a CONSTANT PREDICTION, iony know that pkzip and

trouble installing centos 6.8
Dear all, I'm having trouble installing Centos 6.8, in a VM using VirtualBox, and hoping that someone on this distribution can help. I'm running VirtualBox Version 5.1.4 r110228 (Qt5.5.1).

Creating new instances from original ones
I have a question about data mining. I have a dataset of 70 instances with 14 features that belong to 4 classes. As the number of each class is not enough to obtain a good accuracy using some classifiers( svm, rna, knn) I need to "oversampling" the number of instances of each class. I have heard that there is a method to do this. It consists in generating these new instances as follows:

Mixed models fixed effects
Dear All, This may sound like a dumb question but I am trying to use a mixed model to determine the predictors of bat activity along hedges within 8 sites. So my response is continuous (bat passes) my predictors fixed effects are continuous (height metres), width (metres) etc and the random effect is site - can you tell me if the fixed effects can be continuous as all the examples I have

Acls
Hi I have some problems with setting permissions on my share. I think it has to do that I didn?t configure this If you use the winbind 'ad' backend on Unix domain members and you add a gidNumber attribute to the Domain Admins group in AD, you will break the mapping in idmap.ldb. Domain Admins is mapped as ID_TYPE_BOTH in idmap.ldb, this is to allow the group to own files in Sysvol on a

Multiple density plots on 1 graph
I want to overlay 50 denisty plots on a single plot. For each plot there are 10,000 data points and i want the empirical density of the data. I have not been able to find an easy way to achieve this (I have scoured the manula and website so sorry if I missed it!), does anyone have any suggestions? Thankyou.

Changing a logical matrix into a numeric matrix

Generating input population for microsimulation
Hi all, I've been struggling with some code and was wondering if you all could help. I am trying to generate a theoretical population of P people who are housed within X different units. Each unit follows the same structure- 10 people per unit, 8 of whom are junior and two of whom are senior. I'd like to create a unit ID and a unique identifier for each person (person ID, PID) in the
