Second, the enforcement level can be correlated with unobserved institutional and development time-varying characteristics at the province level (not captured by the province fixed effects or province-specific time trends), generating a spurious correlation with compliance.
Storms may develop unobserved in these remote places and sweep down suddenly on midocean islands or continental coasts.
LCGA is a kind of mixture modeling, using a categorical latent variable to capture unobserved heterogeneous classes in the development of an outcome over time, with growth parameters presumed to be invariant within classes.
Further, unobserved differences in communities' trajectories of development can additionally bias the effect of mothers' education on daughters' circumcision.
This pattern is consistent with a negative correlation between the unobserved endowment components positively related to skill development and school attainment and the endowment components positively related to biological development (Behrman and Rosenzweig 2004), and skilled job tenure.
We have adopted a LCGA technique, which is a rigorous statistical method that can capture unobserved heterogeneous latent classes of SPD in the development of the cognitive-emotional and psychosocial outcome over a two-year time period.
Conversely, the timing and fate of the development component deals with the eventual (sometimes unobserved) probability of a developmental event occurring.
Large sample numbers within genetically defined metapopulations also allows the development of biostatistical methods to estimate the frequency of unobserved or rare haplotypes ("haplotype frequency surveying method").
In the interest of increasing room for policy implications and controlling for the unobserved heterogeneity, the analysis is decomposed into the fundamental characteristics that human development is based on: income levels, legal origins, religious dominations, political stability, landlockedness and resource-wealth.
Which part of a child's development is therefore caused by the mother staying at home, and which by these unobserved factors?
