similar to: 600 people's time series

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

Hi all ! Running this: @payout = stub_everything(:id => 141) Payout.stubs(:find).with(@payout.id).returns(@payout) Generates this warning: ./test/functional/payouts_controller_test.rb:22: warning: Object#id will be deprecated; use Object#object_id What am I missing ? :id is a fairly frequent method to override in Rails-based applications. I''m using Mocha from

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

I am trying to extract one particular piece of data(Float) from all the data returned by yahooKeystats, but thus far I'm having no luck.

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

OK, this is working with the Windows 7 clients now. Looks like it was just a reboot. Now I have an issue with the Windows 10 clients... I'll open a new thread about that...

The bounty stands at $5,500. I'm seriously considering taking a shot at it if I can find a decent T.38 provider to test with (I'm still hoping for reliable PAYG T.38). It looks like a lot of very smart people have done a lot of very hard work (t38modem, spandsp) that would go towards getting this working. At this point it appears to be mostly a matter of integration

Hello, I have some trouble in terms of using integrate function in R. f1 is a function of p and x where x is supposed to be a vector. (See the code). Then I want to write function f2 which is a function of the vector x after I integrate out p. Can some one give me some help? Many thanks! Hannah > f1 <- function (p,x) + { + y <- p*x+(1-p)*x^{2} +
