Traditional statistical analysis of data assumes that data consist of repeated samples. But in applications it may not be natural to look at the data in this way. An example is the experiment of tasting of food samples. There may be given judges that taste on some specific types of food. Neither the judges nor the types of food may be considered as the sample dimension. In the analysis of such data we do not distinguish between role of score and loading vectors. Some optimization procedures are used to find good score vectors and some other optimization procedures to find optimal loading vectors. When these two have been found it is judged how we should proceed with the present step of the analysis. By using these procedures it may be possible to get better description of data than traditional methods give. The disadvantage may be that we do not have the well-known properties of the score and loading vectors, for instance the score vectors may not be orthogonal.
