Question

Where does ArcView specify the 'm' and 'u' probabilities for each field of each address style?

Answer

ArcView specifies the 'm' and 'u' probabilities for each field of each address style in the .mat files located in the installation geocode directory.

These files are:

us_addr1.mat - used in US Streets with Zone address style.

us_addr2.mat - used in US Streets address style.

us_intsc.mat - used in both US Streets with Zone and US Streets
address styles.

key_1.mat - used in Single Field address style.

zip4.mat - used in Zip+4 address style.
