aThe time and bilateral country pair fixed effect model is the classical three-way fixed effects model of Egger and Pfaffermayr (2003), and it is the most commonly used in gravity models (Micco, Stein, and Ordoñez 2003). Baldwin and Taglioni (2006) argue that this specification is superi...
The proportional hazards assumption of the Cox model does sometimes not hold in practise. An example is a treatment effect that decreases with time. We study a general multiplicative intensity model allowing the influence of each covariate to vary non-parametrically with time. An efficient estimation...
Selecting aλvalue a priori can be tricky. For instance, it seems likelambda = 20is too high since the number of groupsKis underestimated. We suggest iterating over a comprehensive range of candidate values to trace out the correct model. To specify a suitable grid, create a logarithmic sequ...
Microsoft Corporation unveiled Tuesday a new hardware personal computer (PC) model together with a new software operating system slightly different from its previous Windows version. China issues regulation on online news service Cooperation between Chinese online news service providers and entities with fo...
For each model, we run a ‘forced’ simulation where the bifurcation parameter μ is increased linearly across the interval [μ0, 0], and a ‘null’ simulation where μ is fixed at μ0. The initial value for the bifurcation parameter μ0 is drawn from a uniform distribution across all...
Simple, reusable way to set up a cell from a view model. Eliminate the extra step of registering a cell class or nib to associate it with a reuse identifier. Use a generic registration type which incorporates a configuration closure for setting up a new cell from a view model. Cell conten...
found that time granularity of 5 min was better than 2 min in predicting effect. The 2 min graininess data has great volatility, and the 5 min data smooths out some useless information brought by data fluctuation. Moreover, the 2 min graininess prediction model can only cover the...
Performance estimation aims at estimating the loss that a predictive model will incur on unseen data. This process is a fundamental stage in any machine le

In this model, the predictability of words per se has no direct effect on their reading time; unpredictable words take longer to process only because they contain unpredictable fragments. This would seem to make it difficult to test the theory, because experimentally we can only measure word pred...
