| Jan 25, 2016 at 9:36 | comment | added | Jamgreen | Can you give an example if I just have 10 numbers: $[1, 2, 8, 7, 4, 3, 2, 4, 9, 1]$? | |
| Jan 25, 2016 at 7:39 | comment | added | seanv507 | No, you start with a guess of the parameters of the two normal distributions , based on these you allocate the data to your two normal distributions (by max likelihood) , then you recalculate the parameters of the distributions using your data split, and repeat until convergence. | |
| Jan 25, 2016 at 7:24 | comment | added | Jamgreen | I guess I can assume that follow a normal distribution. I have just read a bit about EM algorithm, but in the EM algorithm, it seems that I know which results belong to which group. | |
| Jan 25, 2016 at 7:06 | comment | added | seanv507 | It may be possible if you provide more information Eg if you specify the family of distributions from which the sample comes... You might want to look at expectation maximisation (EM) algorithm | |
