Description

This function fits the distribution of a input vector with mixture of Normal and Uniform distributions and returns the BIC score for the model.

Usage

1

Arguments

Y

input vector. In the context of subclonality inference, Y can either be sAGP or CCF values from one sample.

Details

The model is: Y~ A*U(0,1)+(1-A)*Normal(mu,sigma), where A, mu and sigma are parameters to be fitted.

Value

a list containing the following elements:

BIC

BIC score from the model.

fit

a vector containing three numbers, in the order of fitted A, mu and sigma.
