PatraSen_dist_calc {admix} | R Documentation |
Compute the distance to be minimized using Patra and Sen estimation technique in admixture models
Description
Compute the distance to be minimized using Patra and Sen estimation technique by integrating along some given grid the appropriate distance. For further developments, see 'Details' below.
Usage
PatraSen_dist_calc(data, gridsize = 200)
Arguments
data |
Sample where the known component density of the admixture model has been transformed into a Uniform(0,1) distribution. |
gridsize |
Gridsize to make the computations. |
Details
See Patra, R.K. and Sen, B. (2016); Estimation of a Two-component Mixture Model with Applications to Multiple Testing; JRSS Series B, 78, pp. 869–893.
Value
a list containing the evaluated distance and some additional information.
