Type PARAFAC to get help on the I/O format of the PARAFAC algorithm.

To calculate a one-component PARAFAC model type

`Factors = PARAFAC(X,1);`

Where `X`

is the data and` 1`

is the number of factors to extract.

Remember that in PARAFAC the models **are not nested**, so if a two-component model

is to be estimated one can not use the one-component model as a basis as in ordinary

two-way PCA.
