Attempts to estimate the parameters
of the underlying Gaussian distribution from the given samples.
The only information used is the sum of each sample,
although the samples' data are simulated (to spare data input).
Indeed, in the typical industrial applications, usually only the sums
are available, not the individual values.
An option to equalize the sample sizes is provided, for
simplicity. (The sum of the sample sizes must be adequately divisible.)
An attempt is made to estimate σ,
needing further (thorough) research.
Other suggested data: do not equalize. |
