From: Error and bias in under-5 mortality estimates derived from birth histories with small sample sizes

Metric | Formula | Interpretation |
---|---|---|

Error | $\hat{{q}_{0}}-{q}_{0}$ | Measure of bias, in absolute terms. |

Relative error | $\frac{\hat{{q}_{0}}-{q}_{0}}{{q}_{0}}$ | Measure of bias, in relative terms. |

Absolute error | $|\hat{{q}_{0}}-{q}_{0}|$ | Measure of the magnitude of the difference between the estimates and true mortality, in absolute terms. |

Absolute relative error | $\left|\frac{\hat{{q}_{0}}-{q}_{0}}{{q}_{0}}\right|$ | Measure of the magnitude of the difference between the estimates and true mortality, in relative terms. |
