Simulated Cucurbit Tobamovirus Testing Dataset for Illustrating Possible Data Format Only

This dataset contains wholly simulated and not particularly realistic data. It is intended to demonstrate the format of a possible dataset of tobamovirus testing results for cucurbit imports into Australia.

If permission is obtained to publish real data, the real data will contain de-identified data on testing for virus presence in cucurbit seed lots where importation into Australia was attempted, over a period between 2019 and 2021. Each row represents a seed lot. For each lot, a number of groups of 400 seeds were tested for tobamovirus contamination, returning a presence or absence result for each group.There is no identifier or name representing the lot, consignment, importer or source country. The ID variable on the file was randomly assigned.

Other authors will be added to the real data page subject to their permission and preference.
