1	triangle.pair.test (nb.good, nb.answer)

`nb.good`	number of panelists who identify the odd sample
`nb.answer`	number of panelists who make the triangle test

Triangle test: panelists receive three coded samples. They are told that two of the sample are the same and one is different. Panelists are asked to identify the odd sample.

Returns

`p.value`	the p-value of the Triangle test;
`Estimation`	estimation by Maximum Likelihood of the number of panelists who really perceive the difference between the products;
`ML`	Maximum Likelihood of the estimation of the number of panelists who really perceive the difference between the products;
`minimum`	minimum of panelists who should detect the odd product to can say that panelists perceive the difference between the products.
