population.test.MinPv {BrainCon} R Documentation

## The one-sample population inference using Genovese and Wasserman's method

### Description

Identify the nonzero partial correlations in one-sample population, based on controlling the rate of the false discovery proportion (FDP) exceeding c0 at \alpha. The method is based on the minimum of the p-values. Input a popEst class object returned by population.est.

### Usage

population.test.MinPv(
popEst,
alpha = 0.05,
c0 = 0.1,
targetSet = NULL,
simplify = !is.null(targetSet)
)


### Arguments

 popEst A popEst class object. alpha significance level, default value is 0.05. c0 threshold of the exceedance rate of FDP, default value is 0.1. targetSet a two-column matrix. Each row contains two index corresponding to a pair of variables of interest. If NULL, any pair of two variables is considered to be of interest. simplify a logical indicating whether results should be simplified if possible.

### Value

If simplify is FALSE, a p*p matrix with values 0 or 1 is returned, and 1 means nonzero.

And if simplify is TRUE, a two-column matrix is returned, indicating the row index and the column index of recovered nonzero partial correlations. Those with lower p values are sorted first.
