These were mainly computed for illustrating the gender gap at different levels of the proficiency distribution and being able to compare gender differences across studies.
The true person proficiency distribution was simulated to depend on both background variables.
The comparisons that we report below between the results produced from the original PISA 2006 analyses and those obtained from the five rotation models are first those for the proficiency means and standard deviations, second those for the percentiles of the proficiency distributions, and third those for the correlations between proficiency and the context constructs.
To our knowledge, this is the first paper to examine the extent of heterogeneity across segments of the conditional wage distribution for the returns to Spanish language proficiency.
Their IVQR estimates suggest that the impact of foreign language proficiency is stronger at the top of the wage distribution for half of the countries, even though there are significant differences between countries.
Their IVQR estimates suggest that the impact of foreign language proficiency is stronger at the top section of the wage distribution for half of the countries analyzed, even though there are significant differences between countries.
In line with our discussion above, the prior on θ i is conditioned on race, age, census region, and urban/rural status, thereby allowing for the possibility that there are differences in distributions of proficiency for blacks and whites of different age groups, census regions, and urban/rural status.
Categories of English-speaking proficiency (speaks English only, very well, well, or not well) and education were grouped (Table 1) according to the distributions for each subgroup to overcome sparse numbers in the sub-categories.
Our mismatch indicator is based on the minimum and maximum skill requirements by occupations, which are estimated as the minimum ((widehat {min}_{j})) and maximum ((widehat {max}_{j})) of the country-occupation distribution of proficiency for those workers who report neither feeling the need of training nor feeling to be able to do more demanding jobs.
Around 50% of students don't pass the state proficiency exams for literacy.
