Title: Estimating Sensitivity of Laboratory Testing for Influenza in Canada through Modelling Document date: 2009_8_18
ID: 06boh550_8
Snippet: Sensitivity was calculated as the number of influenza positive tests divided by the number of influenza positive tests plus the model-estimated number of false negative tests, or equivalently, the estimates of sensitivity for influenza A and B are given by 1/ (1+b 5 ) and 1/(1+b 6 ) respectively. The false negative rate is 1 minus sensitivity. While the null value for b 5 is zero, which indicates no statistical association between the number of i.....
Document: Sensitivity was calculated as the number of influenza positive tests divided by the number of influenza positive tests plus the model-estimated number of false negative tests, or equivalently, the estimates of sensitivity for influenza A and B are given by 1/ (1+b 5 ) and 1/(1+b 6 ) respectively. The false negative rate is 1 minus sensitivity. While the null value for b 5 is zero, which indicates no statistical association between the number of influenza positive tests and the number of influenza negative tests, the corresponding null value for sensitivity is 1.
