Hi there, I have a data frame DF of over 600 people's short term trade data in time order. Below is the simplified structure of the data. id invest payout [1] 1 10 -1 [2] 1 33 33 [3] 1 20 -5 [4] 2 200 33 [5] 2 33 -20 [6] 3 5 -5 [7] 3 5

Dear List, Below is a simple, standard loss model that takes into account the terms of an insurance policy: deductible <- 15 coverage.limit <- 75 insurance.threshold <- deductible + coverage.limit tmpf <- function() { loss <- rlnorm(rpois(1, 3), 2, 5) sum(ifelse(loss > insurance.threshold, loss - coverage.limit, pmin(loss, deductible))) } net <- replicate(1000000, tmpf())

I thought I would write a lottery number generator since I have not had any luck winning the big jackpot - http://megamillions.com/. So far, after over 1.2 million tries, I still have not hit all the numbers from yesterday: 2, 17, 22, 32, 51, 35 (last one is the mega ball). Fun little project that and I thought others would be interested. Let me know if you have a cleaner implementation in mind.

Hi, I'm an R newbie and I've been struggling with a optimization problem for the past couple of days now. Here's the problem - I have a matrix of expected payouts from different stock option strategies. Each column in my matrix represents a different stock and each row represents the return to the strategy given a certain market move. So the rows are not a time series of percentage

Hi , i am trying to get this loop in my r program to work but it is not giving me the results that I desire. I am trying to model an insurance contract where there are n securities that have a fixed likelihood of default vector(data[i,2]) and a payout vector(data[i,1]). i need to price the value of stop losses at the security level and at the portfolio level. to do this i created two while loops

We''re using Mocha stubs to stub out a slow-performing network request in a Test::Unit class. But naturally, we don''t want to stub it out in the few tests that actually verify the functionality of that network request. Is there a way to do the stub in "setup", but override it for the few tests that need the original functionality? (I realize that in this case, the

On a machine with virtual networking is enabled and two ether net controllers eth0/192.168.1.2 and eth1/192.168.1.3 and having SAMBA smb.conf set to: dns interfaces = lo br0 is there a chance for: 1) The system not to boot with DNS working 2) The DNS server bounce between eth0 and eth1 3) The DNS server portion work on boot sometimes on eth0, but when software restarted only work on eth1 or

Hi guys, I''m running mocha (0.3.2) against Rails core and just found an issue where the mock doesn''t go away after the test is run. For example: def test_reset_bang_doesn_reinstall_named_routes ActionController::Routing::Routes.named_routes.expects(:install).never @session.reset! end def test_zzz puts ActionController::Routing::Routes.named_routes.inspect

I''m simultaneously getting into using Mocha and RSpec-style tests (courtesy of the simply_bdd plugin) and I''m struggling with some issues while trying to organize my specs/test. Here''s a code example illustrating the problem: context "update cliient invalid data" do include ClientsControllerSpecHelper specify "should render edit form" do

I''m writing quite a few specs lately that use Ruby''s Timeout::timeout functionality, making sure that timeout errors are properly handled and everything flows right when some command line tools timeout. I like being able to use Mocha''s #returns right now to force a method to raise a TimeoutError, but I know that usage is going away at some point. I''d like to

I changed the initrd to 2.6mb and that memory block is still exactly at 23852 / 14464 / 14464. Actually the process size is around 12 mb when pygrub is counting down to boot, then jumps up to 14+ mb

Hello :) Having just gone through the (admittedly simple) API of Mocha to learn how it works, I wrote a quick guide (190 lines) to help others get up to speed. I''ve attached it as RDOC and as HTML. It is a first draft - please help me improve by giving feedback ! Contents : Overview - Quick overview of Mocha Unit testing, mock object and stubs - Very quick introduction to mock
