How do we combine errors, in biology? The delta method
Published at November 22, 2024 · 7 min read
In a recent post I have shown that we can build linear combinations of model parameters (see here ). For example, if we have two parameter estimates, say Q and W, with standard errors respectively equal to σQ and σW, we can build a linear combination as follows:
Z=aQ+bW+c
where a, b and c are three coefficients. The standard error for this combination can be obtained as:
