Lab 6 Help/Hints: Line Transect and Point Count Analysis

1. If you are having errors while running an analysis (convergence error), try deleting the "uniform" key function and re-running the analysis.  It can give you troubles at times.

2. In the results section, the table should include the key function and series expansion (the model it fits), the density estimate, the standard error of the density estimate and the 95% CI of the density estimate.

3. In the point count results, you will see two graphs.  One is the detection probability plot and the other is the probability density function.  Ignore the probability detection function graph.

4. Here is a format to follow for your results table:

Method / Strata Key Function/ Series Expansion Density Density 95% CI f(0) f(0) 95% CI ESW ESW 95% CI
Line transect              
Point count
