# h: Bias correction function from Pang et al. (2009). In sparsediscrim: Sparse and Regularized Discriminant Analysis

## Description

This function computes the function h_{ν, p}(t) on page 1023 of Pang et al. (2009).

## Usage

 1 h(nu, p, t = -1) 

## Arguments

 nu a specified constant (nu = N - K) p the feature space dimension. t a constant specified by the user that indicates the exponent to use with the variance estimator. By default, t = -1 as in Pang et al. See the paper for more details.

## Value

the bias correction value
