PANELIPERF: Panelists' performance according to their capabilities to dicriminate between products
Description
Computes automatically P-values, Vtests,
residuals, r-square for each category of a given qualitative variable (e.g. the
Panelist variable);
Computes the agreement between each panelist and the panel results;
Gives the panel's results (optional).

Outputs
Returns a list including the following elements (see also the outputs of the panelperf function):
prob.ind |
a matrix which rows are the panelists, which columns are the endogenous variables (in most cases the sensory descriptors) and which entries are the P-values associated with the AOV model |
r2.ind |
a matrix which rows are the panelists, which columns are the endogenous variables (in most cases the sensory descriptors) and which entries are the R-square associated with the AOV model |
| agree.ind | a matrix with as many rows as there are panelists and as many columns as there are descriptors; the entries of this matrix are the correlation coefficients between the product coefficients for the panel and for the panelists |
| res.ind | a matrix which rows are the panelists, which columns are the endogenous variables (in most cases the sensory descriptors) and which entries are the residuals associated with the AOV model |
