Below is a graph of the Post-Reconstruction Party
System in the same form as Figure 4.1 (p. 60) of our
book.
The Pearson correlations for the DW-NOMINATE data with the
original D-NOMINATE results are .94 for the House Chamber Means,
.96 for the House Winning Policy Means, .91 for the Senate Chamber Means,
and .96 for the Senate Winning Policy Means. A visual comparison of the
graph below
with Figure 4.1 show that they are essentially identical throuugh the
100th.
