      Stat Pharm - of course! Really appreciate the breakdown and your content. Seems like you have a good knowledge of such things! Appreciate your shared knowledge!
      This video really helped clarify some of the questions I had after reading the packages Vignette.

    Very informative video. Question - Can you please tell how you change a resource value? If I change it, it keeps the same environment unless I start over. I'm also guessing that this is changed in the script instead of the editor itself but would appreciate how you modify resources, etc. Thanks.

  • @aishamuhammad2543
    @aishamuhammad2543 5 ปีที่แล้ว

    What about the service rate?
    Does the data strictly follows normal distribution? Or is normally distributed? Please help me out

    • @aishamuhammad2543
      @aishamuhammad2543 5 ปีที่แล้ว

      My arrival and service rates are deterministic. How can i simulate the queuing system with deterministic arrival and service rates? Help me pls, am a research student

    • @StatPharm
      @StatPharm  5 ปีที่แล้ว +1

      @Aisha Muhammad put a fixed number rather than a distribution in your function. Suppose you want to add a service time of 15 time units: all you need to do is to remove "timeout(function() rnorm(1,5)) %>%" and put "timeout(function() 15) %>%" instead. Hope this helps.

      also you are referring to an older video 2017, please use 2019 version th-cam.com/video/uIwIdPR3UAc/w-d-xo.html you can watch the 2 video parts of 2019 version, download the R script and contact me if you still face any issues.
