Semiparametric Estimation of a Noise Model with Quantization Errors

  • Published 2009


The detectors in mass spectrometers are precise enough to count ion events, but in practice large quantization errors affect the observations. To study the statistics of low intensity chemical noise, we model the detector signal as X = ⌊τ N⌋ and estimate both τ and N in a semi-parametric approach where the integer valued random variable N represents the… (More)
