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

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)).

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

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

Please help(urgent) - How to simulate transactional data for reliability/survival analysis
Hi friends, I haven't done such a simulation before and any help would be greatly appreciated. I need your guidance. I need to simulate end to end data for Reliability/survival analysis of a Pump ,with correlation in place, that is at 'Transactional level' or at the granularity of time-minutes, where each observation is a reading captured via Pump's sensors each minute.

Thank you Jim, The code did assist me to get the what I needed. Also, I learnt that there are different types of dashes (en-dash/em-dash/hyphen) as explained on this site : http://www.punctuationmatters.com/hyphen-dash-n-dash-and-m-dash/ I achieved it by executing below command after going through this page on stackoverflow:

Please assist -- Unable to remove '-' character from char vector--
Hi, I have a char vector with year values. Some cells have single year value '2001-' and some have range like 1996-2007. I need to remove hyphen character '-' from all the values within the character vector named as 'end'. After removing the hyphen I need to get the last number from the cells where there are year range values i.e if the cell has range 1996-2007, the code

CPU Temprature
Hi; While using xen-3.0.2 with 2.6.16.28 kernel CPU (Intel(R) Pentium(R) M processor 1.73GHz) temprature is inreasing up to 104 C (/proc/acpi/thermal_zone/THRM/trip_points reports 105 C is critical for CPU) while idle or no domU working with very low system load, and if i start to use domU, sometimes system freezes or reboots for heat. But the same kernel just without Xen works normally and

Sending snmp traps from a serial ups
Hello, I want to poll ups information (status, load, temprature etc.) from a Linux server with snmp. The ups is connected with a serial cable and I'm using nut. It is possible to transfer Information from ups nut to the linux smnpd (with some scripts?) and to make some extention to the mib database. I know, my question is not ups nut related. Mit freundlichen Gr??en / Best regards Markus

Unexplained shutdown of VM on upgrade of libvirt package
I am running KVM on Centos 6.3 and am seeing an unexplained shut down of two guests. The libvirt package was upgraded to libvirt-0.10.2-18.el6_4.4.x86_64 at the time of the shutdown. Only the two guests shown below was affected, while 9 others running on the same hypervisor were not. Can some one help me to find the cause please ? Regards Chandana GUEST #1 ======== 2013-04-10

Upgrade from 3.8.15 to 3.12.5
I believe the peer rejected issue is something we recently identified and has been fixed through https://bugzilla.redhat.com/show_bug.cgi?id=1544637 and is available in 3.12.6. I'd request you to upgrade to the latest version in 3.12 series. On Mon, Feb 19, 2018 at 12:27 PM, <rwecker at ssd.org> wrote: > Hi, > > I have a 3 node cluster (Found1, Found2, Found2) which i wanted
