As a result of neural classification of the table,
ClassifierXL marks the rows of the table with a
cluster number to which this row belongs. For example
you have a table with geographical data that you
need to classify.
Step 1. You click on ClassifierXL from the menu
in MS Excel
After the launch of the program, you will see
the ClassifierXL dialog box.
Step 2. Using the mouse, choose the range of
numerical data of the table that you want to classify
(Source data), and indicate the cell number from
which to start recording the cluster markers (Output).
3. Set output formatting parameters:
- Split to multiple columns: when
selected, a column will be created for each
cluster. For each item, if it belongs to
that cluster, a "1" will be displayed in the
cluster cell. Otherwise, the cell will
contain a "0".
- To one column: when selected, a single
column is created and for each item, a
cluster number is inserted into the cell for
that column.
- Set autofilter: with this selected, you
will be able to review the table rows being
filtered.
- Draw charts: creates charts for the
output data.
- Calculate averages: provides the
averages for each category of the data items
used in the categorization. In most cases,
this information is extremely important. By
comparing the average of a category to the
total average and averages of other
categories, the key characteristics of a
category can be determined.
- Calculate weighted average: calculates
the relative importance of each quantity on
the average.
- Calculate minimums: calculates the
minimum data values for each category.
- Calculate maximums: calculates the
maximum data values for each cluster.
- Calculate cluster weight: calculates the
weight of each cluster, which represents the
percentage of items belonging to the
cluster.
- Set colors: checking this option
highlights the data from each category in a
different color.
- Sort table by clusters: sorts the
original table by clusters.
- Convert table to range: converting table
formatting to the data range.
Step 4. Click on the Classify button and get
the following results:
We have three clusters with the following specific
weights.
You can see that 26% of countries fall in Cluster
1, 21% in Cluster 2, and 52% in Cluster 3.
On the basis of Cluster Profile Chart analyses
the following description could be made:
Cluster 1 is a category of countries with big
populations, population growth rate below the average,
big land and water areas, many irrigated lands,
and growth in Gross Domestic Product over the average.
Cluster 2 is a category of countries with population
above the average, population growth that is maximal,
water and land areas are small but with irrigated
land exceeding the average, and GDP growth somewhat
below the average.
Cluster 3 is a category of countries with populations
6 times lower than the average, standard population
growth, water area considerably lower than average,
area of irrigated land far below the average, and
real GDP far below the average rate.
