Hi Ross

DOS PATN used two strategies for summarising variables across groups. Measures of central tendency (mean, median) and dispersion (range, standard deviation) were the norm for ‘continuous data’.

The alternative of using ‘constancy’ (the tendency for a variable to occur in all objects in a group) and ‘fidelity’ (the tendency for a variable to be isolated to one group) were more useful as group statistical summaries for presence/absence data.

At the moment, PATN uses only measures of central tendancy and dispersion. I’ll look into including an option for constancy and fidelity.

Re exports, I thought it was better to export the lot just in case you wanted to continue the analyses. I figured it was far easier to delete the extrinsics than to add them.
