From: Modeling observations with a detection limit using a truncated normal distribution with censoring
Performance of Maximum Likelihood Estimate for σ as Function of Sample Size. The vertical dashed black line on the left figure corresponds to zero bias. GS = Gold Standard, i.e., uncensored observations with truncation adjustment; Uncens NT = Uncensored data with no truncation adjustment; DL = detection limit; Tobit = Tobit censored regression with no truncation adjustment; tcensReg = Censored regression with truncation adjustment
