A unified approach to false discovery rate estimation

BMC Bioinformatics

Table 3 Various choices of normal truncation points implemented in "locfdr".

Version	Released	Truncation Point	Reference
1.1–1	July 2006	z₀ = 2
1.1–3	December 2006	$z_{0} = \hat{μ} + b \hat{σ}$ with b = 3.55 – 0.44 log₁₀(m), $\hat{μ}$ = median(z_i) and $\hat{σ}$ = IQR(z_i)/1.349.
1.1–6	November 2007	as version 1.1–3, but with b = max(1, 4.3m^-0.112966)	[28]

Note that $\hat{μ}$ and $\hat{σ}$ are robust location and scale estimates, respectively.
