Direct drivers of deforestation in Amazon countries Cattle ranching Cattle ranching is the leading cause of deforestation in the Amazon rainforest. In Brazil, this has been the case since at least the 1970s: government figures attributed 38 percent of deforestation from 1966-1975 to large-scale cattle ranching.
The sampling frequency or sampling rate, fs, is the average number of samples obtained in one second (samples per second), thus fs = 1/T. Reconstructing a continuous function from samples is done by interpolation algorithms.
Many of the studies based on population census data achieve low response rates. Using an adequate Table 2: Minimum Number of Regressors Allowed for Sampling Example Maximum number of regressors if ratio is: Sample size fo r: 5 to 1 10 to 1 Continuous data: n = 111 22 11 Categorical data: n = 313 62 31.
