A Population Viability Analysis Modelling Tool for Seabird Species – Tool Testing: Report for methodology and results for testing of tool 2020
This study involved running a suite of tests to generate a range of Population Viability Analysis models and outputs within the R package, and similarly within the Shiny tool. A range of PVA models were tested within each of the three Shiny modes – Simulation, Validation and Sensitivity. These tests revealed a number of bugs, all to do with default settings within Shiny that needed to be updated to match those within the R package. After these bugs were updated, the Shiny tool produced almost identical output to the R package under all three modes of use. Very minor discrepancies between the two sets of output (Shiny versus R) were expected due to differences in seed matching arising from the automated generation of inputs within the methods used to generate the R outputs in the testing.
