When both variables are subject to error, a straight line may be fitted by minimizing the sum of squared distances of the observed points to the line. Approximate distributions of the slope of this ...

Sequence-specific nucleases have been applied to engineer targeted modifications in polyploid genomes 1, but simultaneous modification of multiple homoeoalleles has not been reported. Here we use ...

Equations that have more than one unknown can have an infinite number of solutions. For example, \(2x + y = 10\) could be solved by: \(x = 1\) and \(y = 8\) \(x = 2\) and \(y = 6\) \(x = 3\) and \(y = ...

A model is given for the behavior of communities and firms in regards to the granting of local firm property tax abatements in a metropolitan area. The model yields a system of simultaneous equations ...
