How to represent the output of MixSIAR?

Open Jwang1990 opened this issue 8 years ago • 2 comments

hello,everyone: If I have run the model with MixSIAR, and “process output”, how can I represent the output in my paper? If I can represent a table or a graph? How to represent the summary statistics in the R console? For example, in the Palmyra Example, Median diet proportions are (27.6% Lagoon, 49.8% Pelagic, 21.9% Reef) for blacktip sharks , and (2.6% Lagoon, 91.3% Pelagic, 6% Reef) for grey reef sharks,why the sum of three source median diet proportion is not 100%, and can we use the means to represent the source proportion?why?

I have found that one of the best ways to present the data is to use a box and whisker plot, but you can only do this if your data is uni-modal. If you have multiple modes then you need to plot the full distribution. You need to use the source means to sum to 100; there is a pretty big fundamental difference in what the mean and median values are. Means are particularly susceptible to the influence of outliers and skewness and as a result median values are often a better description of your data.
