Hello, Is it possible to use ALGLib to fit a line of form y=ax+b. Say I have the following data points: 12 10.1542 13 16.59 14 15.5466 15 22.9597 16 36.8394 17 41.5816 18 51.5024 19 60.026 20 65.1672 21 62.9512 22 72.38 23 72.4192 24 80.0888 25 94.41 26 97.2659 27 95.6868 28 97.6835 29 113.109 30 126.1172 31 113.1448 32 126.4449 33 143.7965 34 118.164 35 142.7557 36 149.0824 37 78.8028 38 153.0144 39 3.17 40 153.94 Can I do this with ALGLib? Which functions are needed for this? Thanks Mike |

Yes, it is possible. Take a look at linreg subpackage. |
