HOA: Compute Hodder and Okell's A and Dispersion Ratio
HOA computes Hodder and Okell's A and Dispersion Ratios described in their article in Simulation Studies in Archaeology (Hodder and Okell 1978; see also Hivernel and Hodder 1984). Run the program by typing: HOA<Enter>.
SEQUENCE OF PROGRAM PROMPTS
File Containing Coordinate and Type Data {.ADF} ?
The program expects the input file to have three variables: X and Y coordinates and a type variable. The type variable, indicating the category of the observation is restricted to the range 0-255, and no more than 30 distinct types numbers within this range may be used.
Listing File {HOA.LST} ?
Output file for the printed listing.
Matrix Output Files: [N]one, [S]quare, [L]ower, [U]pper {N} ?
Form of output files of coefficients to be used by other analysis programs, e.g. a multidimensional scaling program. Typically no further analysis will be done, in which case reply N. Square refers to a square symmetric matrix, U to an Upper (right) triangular matrix without the diagonal, L to a Lower (left) triangular matrix, also without the diagonal. Note that U is the triangular matrix form used by other Antana programs. (These triangular matrices can be printed out using TRIANGLE.
Number of Random Runs {0} ?
A Monte Carlo option not described in the original articles but explained by Kintigh 1990 is included. Briefly, this allows you to assess the actual coefficients against a reasonable random expectation derived by randomly assigning the types to actual points (with the same overall count of each type).

Output File for A: Hodder and Okell's A {HO-A.HOA} ?
Output File for d: Dispersion Ratio {HO-A.Hod} ?
Output File for rbar: Average Distance {HO-A.HOr} ?
If output files have been requested, three possible output files can be obtained. Reply NUL to not write that matrix to a file.
