Logistic Reggresion - Gabrielalm - 07-29-2024 07:24 PM Hello, I need some advice about the built in logistic reggresion function in my hp prime. I don’t understand how this function works. The function says it needs a list and a value of x0 and a value of y0. The function works for a list of x and y data ? or how it works because the list that asks for input must be as follows [1,2,3,4], and this way I can’t enter data pairs (x,y). Thank you so much if someone can help me with my doubt. RE: Logistic Reggresion - rawi - 07-31-2024 04:18 AM Go to Apps - Statistics2Var. You see a spredsheet. Type in your x-variable in Column C1 and y-variable in Column C2. Press the Symb-Key. Set hook in first line. Select Type Logistic. Press Plot-Key. You get a graphic of the dots + function. Press Symb-Key. You will find your logistic function with prameters. I hope this helps a bit.

I looked at the online help screen and realized that this does not do what I expected. I haven't had time yet to look at it more thoroughly, but I will have to study it when I get a chance. RE: Logistic Reggresion - parisse - 08-04-2024 09:34 AM Online help example is misleading. Should be e.g. Pcumul,Pinstant,Ptotal,Pinstantmax,tmax,R:=logistic_regression([2.,3.,4.,5.,4.5],0.0,4.0) Input signification: cumulated production estimated at time 0: 4, instant production at times 0, 1, 2, 3, 4: 2,3,4,5,4.5 If you plot Pinstant from x=0 to 10 you will see a nice Hubbert curve. |
