Finally, with a simple linear regression network, a tighter coordinate can be obtained. The main downside of the technique is its computational cost. The network needs to compute a forward pass for every bounding box proposition. The problem with sharing computation across all boxes was that the...

To do this, we performed a multiple linear regression on the wavelet coefficients at each scale using a selection of known recombination correlates as predictor variables (see Methods). In our initial analysis, we included GC content, exon density, density of THE1B repeat and density of the ...

Following this theoretical framework, the book explores applications involving the Dunnett test, Tukey's all pairwise comparisons, and general multiple contrast tests for standard regression models, mixed-effects models, and parametric survival models. The last chapter reviews other multiple comparison ...
