Other strengths of our study include the rigorous data collection procedures in NHANES and the ability to generate nationally representative estimates, which allows for comparison with other studies that used national samples (6).
Note that since the endogenous variable has five categories, four cut points are estimated, which allows us to compare various levels of the endogenous variable with each other.
An important point in which GPR differs from linear regression, is that the method assumes a probability distribution over the set of functions to be estimated, which allows for determining families of regression functions with specific functional forms.
Applying count data econometrics to a panel data set of Spanish manufacturing firms surveyed in the period 1990 1996, a transcendental production function is estimated, which allows for non-constant elasticities of the R&D inputs.
Furthermore, Reitsma et al. [ 5] show that a BRMA of diagnostic studies enables the correlation between pooled endpoints to be estimated, which allows one to measure the shape of their bivariate relation and construct confidence ellipses.
Additionally, we used generalized estimating equations, which allow the pregnancy outcomes from the same woman to be unconditionally correlated; the two methods gave practically identical estimates and 95% confidence intervals.
In Section 3, we present micro estimates for Italy, which allow us to control for a very wide sources of composition effects.
Finally, we stress the usefulness of estimates (12), which allows one to obtain a rough estimate for the error made using the Jensen inequality when φ is merely Lipschitz continuous.
This yielded parameter estimates for a0, a1, b 0, b1 which allow to estimate the tree height h corresponding to a given stem diameter d in a given calendar year.
