This assumes an even cost per day over the course of the contract – which would obviously not be the case, but it's rather difficult to estimate otherwise.
The WLE could be inserted only for respondents with r=0 and r=k, and the ML estimates otherwise.
Giving preference to estimates for never smokers, if available, and overall population estimates otherwise, the estimate was 1.14 (0.67–1.93), again based on heterogeneous estimates.
If the resulting parallelogram extends at least over receiver locations, save it as an estimated MPC. Otherwise reject it.
For each study, the effect estimate was calculated as the adjusted estimate where present and the crude estimate otherwise.
When available, we pooled adjusted estimates; otherwise, we pooled the unadjusted estimates based on crude data from the individual studies.
If linearity seems reasonable, the relaxed procedure can be used to obtain precise threshold estimates, otherwise, the tracking procedure is recommended.
In Sweden, gestational age is usually based on a second-trimester ultrasound estimate; otherwise, information on the last menstrual period was used.
If there was statistically significant heterogeneity (P < 0.05) the random effect model was used to calculate the combined effect estimate, otherwise the fixed effect method was used.
Some states also provided the LMP information; therefore, a combined gestational age variable was developed that gave preference to the calculated estimate when available and used clinical estimate otherwise.
One of them is that it is important to take the timescale of rate measurement into consideration when using or interpreting evolutionary rate estimates; otherwise, the outcomes could be severely biased.
