Re: [R] speed issue in simulating a stochastic process

Loops are not slow, but your code did a lot of unneeded operations in each loop. E.g, you computed D$id==i & D$t==t for each row of D. That involves 2*nrow(D) equality tests for each of the nrow(D) rows, i.e., it is quadratic in N*T. Then you did a data.frame replacement operation D[k,]$y

Thanks Jeff Newmiller, it is working now. I would like to know, the same kind of configuration can be done in Linux and Solaris platform. Instead of R is mapping to operating system(/usr/share/. /usr/share/lib/) zoneinfo directory. Thanks Vasanth On Fri, Nov 7, 2014 at 1:18 AM, Jeff Newmiller

Re: [R] Daylight Saving Time

R on Windows uses the Olsen timezone database, a copy of which is stored with R in the Program Files directory (e.g. R/R-3.1.1/share/zoneinfo). You could update the file yourself if you can find a corrected version, or download an updated version of R. ---

Re: [R] speed issue in simulating a stochastic process

Matteo, Ah — OK, N=20, I did not catch that. You have nested for loops, which R is known to be exceedingly slow at handling — if you can reorganize the code to eliminate the loops, your performance will increase significantly. Tom On Thu, Nov 6, 2014 at 7:47 AM, Matteo Richiardi wrote: > I wis

I wish to simulate the following stochastic process, for i = 1...N individuals and t=1...T periods: y_{i,t} = y_0 + lambda Ey_{t-1} + epsilon_{i,t} where Ey_{t-1} is the average of y over the N individuals computed at time t-1. My solution (below) works but is incredibly slow. Is there a faster

You avoid the call to cmdscale() by supplying your own starting configuration (see the manual page for the y= argument). You could still hit other barriers within isoMDS() or insufficient memory on your computer. - David L Carlson Department of Anthropology Te
