similar to: Please help(urgent) - How to simulate transactional data for reliability/survival analysis

A small example data set that illustrates your question will be of great value to those trying to help. This appears to be a transformation that you are wanting to do (timestamp to units of time) so a data representing what you have (dput() is handy for this) and one representing what you want to have with any guidance regarding how to use the other columns in you data set (e.g., the event(0/1)).

In principle what you need to do is the following: - break down the time you wish to simulate into intervals. - for each interval, and each failure mode, determine the probability of an event. Determining the probability is the fun part, where you make your domain knowledge explicit and include all the factors into your model: cumulative load, failure history, pressure, temperature,

Thanks Boris and Bret, I was successful in simulating granular/transactional data. Now I need some guidance to transform the same data in format acceptable for survival analysis i.e below format: pump_id | event_episode_no. | event(0/1) | start | stop | time_to_dropout The challenge I'm experience is to generate the 'start' and 'stop' in units of minutes/days from single

Mark, Below is the sampled simulated granular data format for pumps for trial period of 3 months that I need to transform for survival analysis: 3 months = (60*24*90) minutes i.e 129600 minutes pump_id timings events vibration temprature flow pump1 01-07-2017 00:00 0 3.443 69.6 139.806 pump1 01-07-2017 00:10 1 0.501 45.27 140.028

Hi, I need help to simulate data to model pump's failure. Below is thought process to simulate the data: - For each Pump readings are captured via sensors each minute for period of 3 months. There are 10 pumps in total. - The failure rate or occurrences of event in 3 months for each Pump is defined. i.e Pump1 would fail 3 times in 3 months, Pump2 would fail 2 times in 3 months, etc. - The

I am trying to it a particular nonlinear model common in Soil Science to moisture release data from soil. I have written the function as shown below according to the logist example in Ch8 of Pinheiro & Bates. I am getting the following error (R version 2.1.1) *Error in qr(attr(rhs, "gradient")) : NA/NaN/Inf in foreign function call (arg 1)* Below is the function and data. /#

I have a vibration signal coming accelerometer. I converted this signal from* m/s^2* to *mm/s*. Now I am supposed to predict this vibration signal in R using historical data. (Please see the attached picture of vibration signal). Can I use this vibration signal just like that to the prediction using predictive Models or Do i need to do some processing technique before doing prediction? Are there

I'm trying to draw an arrow with a curved shaft on the graph as a straight one looks messy on a detailed graph. I've looked in arrows but it doesn't seem to give an option. larrows doesn't look much more promising. I had a look in the archive and couldn't find anything. Any thoughts?

I'm looking for people who have an xbox360 joystick to help run some tests so I can get information on implementing xinput for wine. The more 360 joysticks plugged in the better. Can you please go to the forum post I made and test: http://forum.freegamedev.net/index.php?t=msg&th=1980&start=0 Thanks, Andrew

Hi guys, I am following this[1] tutorial to install clang. However, I have made a small change in the configure command, and I am running it with '--enable-optimized' option to avoid the debug build. I am getting the errors (given at the end) related to *undeclared identifiers '__NR_*'*. Can someone please provide some input about how to tackle this issue? On my other machine, I

Well Solaris SAS isn''t there yet but anyway just found some interesting high density SAS/SATA enclosures. <http://xtore.com/product_list.asp?cat=JBOD> The XJ 2000 is like the x4500 in that it holds 48 drives, however with the XJ 2000 2 drives are on each carrier and you can get to them from the front. I don''t like xtore in general but the 24 bay (2.5" SAS) and 48

I am bumping this thread because I too have the same question ... can I put modern 3TB disks (hitachi deskstars) into an old x4500 ? If not, would the x4540 accept them ? -- This message posted from opensolaris.org

Hi, I am curious to know about LLVM IR as platform independent feature. I have compiler some C and C++ applications that compiled on Linux 64bit machine, now I want to generate bit code file on Windows 64bit machine. 1) Will this execute without any issues? 2) Do I pass any option for making it operating system portable? 3) Can I generate bit code file also on Linux machine and then run on

Hi guys, I am compiling some programs with clang which use a couple of libraries. When I compile with the command - "clang -O2 -I. -o hello -ldl -llttng-ust hello.c tp.c", it goes successful. My aim is to get the bitcode for these programs but if I try to generate the bitcode with -emit-llvm option, it produces linking issues as follows : (also at - http://pastebin.com/zkmL2SAH)
