Table 2. Statistical power computed for the three proposed test statistics.
Power (%) | ||||||
---|---|---|---|---|---|---|
n = 10 | n = 20 | n = 30 | n = 50 | n = 100 | n = 153 | |
Test statistics | ||||||
CPI-supported paths (S1) | 0 | 0 | 0 | 0 | 0 | 0 |
CPI-supported transmitter in direct contact (S2) | 0.67 | 0.93 | 0.98 | 0.99 | 1 | 1 |
CPI-supported transmitter path length (S3) | 0.75 | 0.96 | 0.99 | 1 | 1 | 1 |
Power was determined for an increasing set of incident colonization episodes, with 500 replicates each time.
