In the Washington dataset, farm animal contact was considered "yes" if the patient reported a history of living or working on a dairy or other farm type or reported a history of contact with cattle, sheep, goats, horses, or pigs; bovine contact was considered "yes" if the patient specified cattle as the type of farm animal.
In the New York dataset, farm animal contact was considered "yes" if the patient reported an occupation of animal farming or a history of farm animal contact; bovine contact was considered "yes" if the patient specified cattle as the type of farm animal.
On the contrary, in an unbalanced panel dataset, farms refers to time series of different length and to different periods (e.g. at the beginning or at the end of the considered interval of time) making results sensitive to changes in the composition of the sample of farms over time.
For the sows/piglet farms two farms were excluded from the dataset (2326 farms remaining) after exclusion of these delivery records, for finisher pigs 22 farms were excluded (4606 farms remaining).
"KisanHub blends diverse datasets like farm, crop, operation records, weather, satellite, commodities, farm machinery, sensors, among others, to provide data-driven decision points," adds Shende.
The second dataset from 58 farm households contains data on agricultural practices, environmental changes, and environmental migration.
The first dataset from 367 farm households1 contains data on farmers' perception of climate change risks or hazards, their impacts on farmland productivity and farm households' risk management strategies.
The following two commands are used to load the EpiContactTrace package and the transfers dataset into R The farm or farms of interest, here called root, are specified through an integer or character vector.
Parameter estimation was performed using a dataset including all farms for which the date of first clinical suspicion was reported to be between 5 July 2006 and 1 November 2006 (inclusive).
The second dataset contained 418 farming sites located throughout the study area.
In addition, a second dataset of active farming sites during a period of 2011 was created for validating the predictive capacity of the model.
