> I summary evaluate the quality of this distribution > I examine the result of a distribution of 1000 random generations of numbers based on 147 or 997 Then L.R results with r and m from the keyboard (yellow arrow and -)įinally, with this set of programs and the proposed sequence of steps : Then Sy and oy from the keyboard (blue arrow and +)Ģ) to evaluate the quality of the linear regression Usage of LBL F to insert the results of LBL H in the stats registers : RCL S // displays basis number generator and stops SIGMA + // adds on stats register the couple for flag 0 on, otherwise it's X y // otherwise directly uses the number of draws for number i STO + T // adds the number of draws of the number i (0.99) in the cumulative registerįS? 0 // uses cumulative register if flag 0 is not set, STO T // stores 0 in the cumulative registers (I will make the step 4 from the keyboard of the calculator)

Then, I made 3 little programs, one for each step 1 to 3. It has on-board (built-in) statistical functions It has a huge memory, easy to adress from 0 to 99. I said to me : it's a job for my HP35s, it can do this ! And I would also like to recover the standard deviation of the data.

I can consider a couple of data as the number (0.99) and its number of draws obtained all along the distributionĪnd, if I manage to position and accumulate each pair on a line, I should get a correlation of 1 for a slope of 10.ġ) make a distribution of 1000 generations between the 100 numbersģ) transfer the results to a statistical structureĤ) collect the calculation of the correlation coefficient of the line and calculate the value of its slope. In perfect world, I can expect a fair distribution of 10 items by number (because 100 x 10 = 1000). In first time, I decided to experiment a distribution of 1000 items between 100 numbers : from 0 to 99. I asked me how to answer to it and I thought of a method Is there any much difference of the random output with these 147 and 997 ? The steps on how to generate random integer is similar to the 997 This book mention using the 147 Algorithm to generate Random Integer. Recently read an old book that teach kid 'Math Algorithm' and one of the topic was about the 'Random Number Generator.' +- Thread: 147 and 997 Random Generator Algorithm ( /thread-16022.html)ġ47 and 997 Random Generator Algorithm - Gamo - 12-08-2020 06:57 AM +- Forum: HP Calculators (and very old HP Computers) ( /forum-3.html) 147 and 997 Random Generator Algorithm - Printable Version
