The application of these weights to analyses conducted using the HEP sample allows us to estimate population effects from the HEP sample.
An important strength of this study is that the use of the population based sample allowed us to study relatively rare conditions during pregnancy.
Our large sample allows us to observe differences across groups not possible in previous studies.
Including different countries in the sample allows us to control for different regulatory regimes across markets and unobserved heterogeneity.
The nature of our sample allows us to trace back to the adoption point and develop a set of reasons-for-adoption from the analysis of the data.
This control sample allows us to estimate the effect of random fluctuations in experimental conditions, such as the thickness and surface roughness of the polymer coating, temperature, etc.
The large (25 × 25 mm2) surface area of the sample allowed us to carry out measurements in incidence angles range ±75° at a laser beam diameter of 4.5 mm.
We extract experimental values of the probe admittance by measuring the voltage reflection coefficient S11 with and without the sample (allowing us to calibrate out to the electrical length of any cables).
Furthermore our family sample allows us to perform an association analysis as well, which provides non-redundant and complementary information.
