Permap- perceptual mapping.
1.
Overall similarity- done for each pair
of object to get similarity for the pair. It is more flexible. We find out
overall similarity between the attributes in the diagram which can be known by
knowledge abt the attributes. Advantage is that it gives which is not on the mind
like the black box of the mind attributes. Disadvantage is to have thorough
knowledge abt the attributes
2.
Attribute based- Rating of attributes is
given by the people and then the rating is given is attitude based permap this
is based on the knowledge of the other people. Advantage is simpler compared to
similarity. It is done on the scale of the attributes and rating is given to
the people. It develops something which is not done by our side in rating scale
Took example of soft drinks in excel and
pairs were given rating in between 0-9 and given higher rating that is similar
pairs. In this we take average of the pair rating and here higher the average
higher the similarity. In the distance matrix 1 and 1 represent higher
similarity. It can be a similarity matrix or dissimilarity matrix in which the
1 or 0 in the diagonal represent the matrix. Then copy the matrix in row and
save it in note pad and load the file in permap software. There are minor
differences in the map created in permap it is due to different laptops and
there configurations.
In permap to check the minimum distance in
the diagram we use auto repeat and auto stop.
By use of hierarchical clustering we can
develop matrix on proximity matrix and can use it in permap software
Park objects in permap leads to remove a
variable form the mapped data. By this mapping we can segregate the map and the
perception in each dimension. Whenever the value drops substantiallyit is 3
dimensional.
