    Hii Thank you , Great work.
    However may I ask if you have video for Linear Regression - Associative Model.
    TIA.

      Hello! I currently have no video for that. But you can solve some using your scientific calculator. Just treat the period as x, and the actual values as y. Then project the value using the line equation, y = a+bx

    Hello po, bakit po iba yung formula compare sa iba (Books: QA for Management 15th) FITt + alpha (At - FITt)?

      @@TheMorgalion I guess it’s based on different derivations, but it should provide the same answers.

    all good, but you forgot to talk about Trend projection and Linear Regression to complete the forecast course

      Hello! Thank you for watching. I focused more on the topics with long hand solutions. Regression methods are mostly done with the aid of calculator functions.

    FIT is subtract po not addition

      Hello. Can you show your reference po? I’m using Operations Management by Heizer and Render. This topic was taught to us since 2010.

      Also, this example was lifted in the textbook. I’m just here to explain how to solve it. Would appreciate if you can provide reliable sources ;)

      Timothy Ochoa hi! saang period ito? Alpha is 0.2 and Beta is 0.4.

    • @EzrhaGodilano
      @EzrhaGodilano  4 роки тому

      If you input the formula in your calculator that should be 0.2(12) + (1-0.2)(13) = 12.80

      What about the the T? Lumalabas sakin 2.52. sayo 1.92. paano nangyari?

    • @EzrhaGodilano
      @EzrhaGodilano  4 роки тому +1

      T = 0.4(12.80-11) + (1-0.4)(2) = 1.92
      Nasa formula mo po yan or pag input sa calcu :)
