Type of Model
Use this parameter to select the type of model to use for testing for rare variant association .
Available models are described in the following table:
Include the weighted sum method described by Madsen and Browning (2009) 1 ; a variable -threshold approach (Price et al . 2010) 2 with or without weights such as PolyPhen-2 scores; models taking the direction of the variant's effect into account, similar to Han and Pan's data-adaptive sum model (2010) 3 ; as well as combinations of these approaches that can be put into the framework described by Hoffmann, Marini, and Witte (2010) 4 .
Perform the kernel-based adaptive cluster method described by Liu and Leal (2010) 5 .
Perform the cumulative minor- allele test described by Zawistowki et al . (2010) 6 .
Perform the C - alpha test described by Neale et al . (2011) 7 when the trait is binary.
