| Calculate |
Estimates μ, σ from the sums of
unequal size (or equal size) samples, from their sums alone. |
(μ, σ ignored). |
| Simulate |
Simulates the table for the sample sizes given, to obtain
μ, σ. |
(sums ignored). |
The items are
assumed Gaussian.
Example data can be inserted (copy, paste)
in the textarea, above, such as:
(a) equal size, 4 samples (n ≡ 20),
columns 1, 2;
(b) "industrial" unequal size, 50 samples
(144 ≤ n ≤ 1296), columns 3, 2
(suggested 'Range', 10).
For μ and σ,
point estimation and confidence intervals are computed.
Draws plots for (1) the Student's statistic, and
(2) the chi-squared statistics. |
