Calculates coordinations by reducing dimensionality using SVD (Singular Value Decomposition).

You can access from 'Add' (Plus) button.

Name1 Column - Set one of name columns to calculate coordinations for.

Name2 Column - Set another column of names to calculate coordinations for.

Value Column (Optional) - Set a column to use as a distance value. If you use do_dist in the previous step, this will be value.

Number of Dimensions (Optional) - The default is "group".

"group" is to see how groups are projected to a new coordinations. This corresponds to u matrix of svd.

"dimension" is to see what direction the new coordinations face. This corresponds to v matrix of svd.

"variance" is to see how data is scattered in each of the new coordinations. This corresponds to d vector of svd. itself.

n_component (Optional) - The default is 3. Set number of dimensions to reduce to. This must be less than the number of subjects and the number of keys.

Number of Dimensions (Optional) - The default is TRUE. Set if data should be centralized to the origin.

Centralize Data - Whether data should be centralized or not.

Output Format (Optional) - The default is "wide".

"wide" - The components will be in columns.

"long" - The component will be in row.
