Method Detail

transform

public double transform(int row,
               int col,
               double value)

Computes the Log Likelihood information between the row and col with value specifying the number of occurances of row with col. This is approximated based on the occurance counts for each row and col.

Specified by:

transform in interface GlobalTransform

Parameters:

row - The index specifying the row being observed

col - The index specifying the col being observed

value - The number of ocurrances of row and col together

Returns:

The new value of the entry located at row, column
