finding the MLEs of IG parameters by EM-Alorithm
...trying to caculate the MLEs for parameters of Inverse Gaussian distribution (in a k-sample problem with common mean) by using EM-Algorithm. I found some package for EM-Algorithm that are useful for missing or incomplete data and are not helpful for solving my problem. (Exactly, the problem is: Let Xij, i=1,..,k , j=1,...,ni, be a random sample from IG(?,?i). So the log-likelihood function is: log(L)=?(ni/2)*log(?i)-?? (?i/2*(?^2)*xij)*((xij-?)^2)+const. Find the MLEs for (?,?1,...,?k) by EM-Algorithm?) Could you please help me with that? I would like to thank you in advance for your help. best...

rbind has confusing result for custom sub-class (possible bug?)
Debugging this issue: https://github.com/Rdatatable/data.table/issues/2008 We have custom class 'IDate' which inherits from 'Date' (it just forces integer storage for efficiency, hence, I). The concatenation done by rbind, however, breaks this and returns a double: library(data.table) DF = data.frame(date = as.IDate(Sys.Date())) storage.mode(rbind(DF, DF)$date) # [1]

distance matrix to coordinate format for spatial stats
Greetings, I would like to use some of the spatial statistics functions in R, but I am having trouble entering data. My data is already in a distance matrix format, not an X Y coordinate format (each Xij cell in the matrix represens the distance from point i to j). Does anyone know of a way to convert a distance matrix to a ppp object in spatstat, or an X,Y coordinate system for other packages? Thanks, Jesse [[alternative HTML version deleted]]
