Some time ago, I inquired about ways to analyze percent cover data, and one of the suggestions was to test for heterogeneity. The snag, however, is that this requires multiplying each cell value by its natural log. My data set has a lot of zero values, which are important to keep; but of course there is no natural log of zero. Is there a way to adjust the analysis to included these zero values? i have not managed to find anything on this.
