Virtual panels are generated using Boostrap techniques in order to display confidence ellipses around products.

|
donnee |
a data frame made up of at least two qualitative variables (product, panelist) and a set of quantitative variables (sensory descriptors) |
col.p |
the position of the product variable |
col.j |
the position of the panelist variable |
firstvar |
the position of the first sensory descriptor |
lastvar |
the position of the last sensory descriptor (by default the last column of |
alpha |
the confidence level of the ellipses |
coord |
a length 2 vector specifying the components to plot |
scale.unit |
boolean, if T the descriptors are scaled to unit variance |
nbsimul |
the number of simulations (corresponding to the number of virtual panels) used to compute the ellipses |
nbchoix |
the number of panelists forming a virtual panel, by default the number of panelists in the original panel |
group |
the number of variables in each group of variables when multiple factor analysis is performed (by default this parameter equals NULL and a PCA is performed) |
name.group |
the names of the groups of variables when mfa is performed (if |
level.search.desc |
the threshold above which a descriptor is not considered as discriminant according to AOV model |
centerbypanelist |
boolean, if T center the data by panelist before the construction of the axes |
scalebypanelist |
boolean, if T scale the data by panelist before the construction of the axes (by default, FALSE is assigned to that parameter) |
name.panelist |
boolean, if T then the name of each panelist is displayed on the |
variability.variable |
boolean, if T a plot with the variability of the variable is drawn and a confidence intervals of the correlations between descriptors are calculated |
cex |
cf. function |
color |
a vector with the colors used; by default there are 35 colors defined |
Panellipse, step by step:
Step 1 Performs a selection of discriminating descriptors with respect to a threshold set by users
Step 2 Virtual panels are generated using Boostrap techniques; the number of panels as well as their size
are set by users with the nbsimul and nbchoix parameters
Step 3 Coordinates of the products with respect to each virtual panels are computed
Step 4 Each product is then circled by its confidence ellipse generated by virtual panels and
comprising (1-alpha)*100 percent of the virtual products
Step 5 Variability of the variables is drawn and confidence interval of the correlation coefficient between descriptors are calculated by bootstrap
A list containing the following elements:
eig |
a matrix with the component of the factor analysis (in row) and the eigenvalues, the inertia and the cumulative inertia for each component |
coordinates |
a list with: the coordinates of the products with respect to the panel and to each panelists and the coordinates of the partial products with respect to the panel and to each panelists |
hotelling |
Returns a matrix with the P-values of the Hotelling's T2 tests for each pair of products: this matrix allows to find the product which are significantly different for the 2-components sensory description; if an MFA is done, hotelling returns as many matrices as there are group, these matrices allows to find the product which are significantly different for the 2-components sensory description of the group, and it returns also a global matrix corresponding to the P-values for the tests corresponding to the mean product. |
correl |
a list with: the matrix of the estimated correlation coefficients and two matrices corresponding to the confidence intervals, min and max, of the correlation coefficients calculated by bootstrap. |
Returns a graph of the products as well as a correlation circle of the descriptors.
Returns a graph where each product is displayed with respect to a panel and to each panelist composing
the panel; products described by the panel are displayed as square, they are displayed as circle when
they are described by each panelist.
Returns a graph where each product is circled by its confidence ellipse generated by virtual panels.
When a Multiple Factor Analysis is performed, returns a graph where each partial product is circled by its confidence ellipse generated by virtual panels.
Returns a graph where the variability of each variable is drawn on the correlation circle graph.
