Sentence examples for bandwidth selected from inspiring English sources

Sensitivity analyses were conducted to assess the overall impact of the bandwidth selected for the kernel matching procedure [ 26] and to examine the degree to which unobserved confounding factors could alter AEE results [ 27- 29] (see Additional file 1: Appendices B and C).
Kernel density estimates of crossover frequency with respect to normalized chromosomal position were obtained with the KernSmooth package (Wand and Jones 1995) for the R language (R Core Team 2012: http://www.r-project.org/), using a Gaussian kernel with bandwidth selected according to the direct plug-in method (Wand and Jones 1995).
