We also used a support vector machine, which is a classification method that is able to deal with highly variable data (Camps-Valls et al. 2004).
The population of this species...where the presence and transmission of introduced avian malaria (Plasmodium relictum) is low (Eggert et al. 2008, Dziel et al. 2010)`;
// Reset `lastIndex` if this regex is defined globally
// regex.lastIndex = 0;
let m;
if ((m = regex.exec(str)) !== null) {
// The result can be accessed through the `m`-variable.
m.forEach((match, groupIndex) => {
console.log(`Found match, group ${groupIndex}: ${match}`);
});
