1. A system for predicting intensities for data points not measured or not measured with a high degree of confidence of a peak using a peak predictor, comprising: a mass spectrometer that produces a plurality of intensity measurements; and a processor in communication with the mass spectrometer, wherein the processor obtains the plurality of intensity measurements from the mass spectrometer, the processor selects a set of data from the plurality of intensity measurements that comprises a peak, the processor assigns confidence values to each data point in the set of data producing a plurality of confidence value weighted data points, the processor selects a peak predictor, and the processor applies the peak predictor to the plurality of confidence value weighted data points of the peak that have confidence values greater than a first threshold level and the peak predictor produces predicted intensities for data points of the peak not measured and/or measured data points of the peak that have confidence values less than or equal to a second threshold level.
