Epidemics were generated using the stochastic simulator from Xu and Madden
(2004). The data consist of the numbers of diseased plants per sampling
unit (out of a total of n = 100 plants in each sampling unit). N = 144
sampling units, and different values for the parameters pattern and
mu were used for the simulations.
Format
A data frame with 864 rows and 6 variables:
| [, 1] | pattern | Either clumped (i.e. aggregated), random or regular. |
| [, 2] | mu | Median spore dispersal parameter. |
| [, 3:4] | x,y | Grid spatial coordinates. |
| [, 5] | i | Number of diseased plants (from 0 to 100). |
| [, 6] | n | Sampling unit size. Here, n = 100 plants per sampling unit. |
