significant difference between Gompertz hazard parameters?
Hello, all. I have co-opted a number of functions that can be used to plot the hazard/survival functions and associated density distribution for a Gompertz mortality model, given known parameters. The Gompertz hazard model has been shown to fit relatively well to the human adult lifespan. For example, if I wanted to plot the hazard (i.e., mortality) functions: pop1 <- function (t) {

multivariate ordinal probit regression vglm()
Hello, all. I'm investigating the rate at which skeletal joint surfaces pass through a series of ordered stages (changes in morphology). Current statistical methods in this type of research use various logit or probit regression techniques (e.g., proportional odds logit/probit, forward/backward continuation ratio, or restricted/unrestricted cumulative probit). Data typically include the

summing two probability density functions from Gompertz hazard model
Hi, r-help members. I have a question about summing two density distributions. I have two samples from which I've estimated hazard parameters for a Gompertz mortality model. With those parameters, I can calculate the PDF (survival function times hazard function) of ages-at-death in a birth cohort subject to the hazard function at each age. I'd like to combine these two density

Gompertz-Makeham hazard models---test for significant difference
Hi, all. I'm working with published paleodemographic data (counts of skeletons that have been assigned into an age-range category, based upon observed morphological characteristics). For example, the following is the age distribution from a prehistoric cemetery in Egypt: naga <-

multivariate ordered probit regression---use standard bivariate normal distribution?
Hello. I have yet to receive a response to my previous post, so I may have done a poor job asking the question. So, here is the general question: how can I run a run a multivariate (more than one non-independent, response variables) ordered probit regression model? I've had success doing this in the univariate case using the vglm() function in the VGAM package. For example:

Inconsistent behavior using 3.1.2 from macOS 10.12.2 to an AFP mount
Hi, I've been attempting to use rsync 3.1.2 to copy files from a macOS 10.12.2 system to an AFP mounted share. The command I'm using is: rsync -avAX -M--fake-super ./testDir ./mnt/testDir/ This works fine and all the extended attributes are copied and readable. I then try to use rsync to copy these files back with: rsync -avAX --fake-super -M--super ./mnt/testDir/ ./testDir2/ This

plotting survival curves (multiple curves on single graph)
Hello. This is a follow-up to a question I posted last week. With some previous suggestions from the R-help community, I have been able to plot survival (, hazard, and density) curves using published data for Siler hazard parameters from a number of ethnographic populations. Can the function below be modified, perhaps with a "for" statement, so that multiple curves (different line

Post disaster, need old BSD 4.7 to talk to current rsyncd OS X
Sorry slightly OT. Looking for the RSYNC community with modern OS X and older BSD OS to advise how to get rsync build / download for BSD 4.7, so I can backup and update .. Alas found an rsync setup (CCC by Mike Bombich) for my just rebuilt Mac Mini to 10.5.8 .. NOW need to find how to save my BSD box so I can upgrade.

plotting survival curves with model parameters
Hello. I am trying to write an R function to plot the survival function (and associated hazard and density) for a Siler competing hazards model. This model is similar to the Gompertz-Makeham, with the addition of a juvenile component that includes two parameters---one that describes the initial infant mortality rate, and a negative exponential that describes typical mortality decline over the

Newbie Q: Controllers and lookup tables - when to initialise
Howdy Gang, in a major controller that has many methods using the same lookup tables for option choices and such, what is the life expectancy of the list instances. Is it useful to set these up in the controller initialize method - or is that utterly dumb? Cheers, Eric

add lowess predicted line to scatter plot
Hi, I have a scatter plot of the variables GNI and Lifeexp (Gross National Income and Life Expectancy, both metric). So I plotted them and I want to add a regression line and a lowess line. I use lowess and not loess because I have missing values. My code: plot(GNI,Lifeexp) abline(lm(Lifeexp~GNI), col="red") y.loess<-loess(Lifeexp~GNI,na. action = na.exclude)

Amount of writes during index creation
Hi, I have had a problem report from a Recoll user about the amount of writes during index creation. https://opensourceprojects.eu/p/recoll1/tickets/67/ The issue is that the index is on SSD and that the amount of writes is significant compared to the SSD life expectancy (index size > 250 GB). >From the numbers he supplied, it seems to me that the total amount of block writes is roughly

snapshot/subvol deletion
Hi, I will send a series patches that add snapshot/subvol deletion soon. But the way to delete snapshot/subvol is far from people''s expectancy. To delete a snapshot/subvol, we need four steps: 1) snapshot/subvol deletion ioctl or rmdir; 2) umount; 3) btrfsck; 4) mount the fs. The reason for this is bug in root back & forward references. In simple terms, the bug prevents us from

demography's lifetable: how to incoporate the parameter "franction of last age interval of life"
Dear list: I have tried demography package in my Ubuntu(10.04). What I interested in was lifetable analysis. Chiang(1984)'s reference have been copied to steeper my learning curve. step by step, the example presented by the textbook also have been examined. In the course I find that the paramter "fraction of last age intervl of life" could not be take as a option in the module

spatial clusters
Dear all, I am looking for a clustering method usefull to classify the countries in some clusters taking account of: a) the geographical distance (in km) between countries and b) of some macroeconomic indicators (gdp, life expectancy...). Are there some packages in R usefull for this? Thanks a lot for your help, Dorina

Hints for Data Mining
Dear All, I am recycling a previous email of mine where I asked some questions about clustering mixed numerical/categorical data. This time I am more into data mining. I am given a set of known statistical indexes {s_i}, i=1,2...N for a N countries. These indexes in general are a both numerical and categorical variables. For each country, I also have a property x_i whose value is known, but
