WebMar 8, 2024 · In this paper, we introduce the robust fitting into pulsar timing to cope with non-Gaussian noise. By modelling the timing process as a linear regression problem, we analyse the relation and difference between the M-estimator and LS methods, providing a robust estimation procedure. WebRobust regressionis less affected by outliers, but it cannot generate confidence intervals for the parameters, so has limited usefulness. Its main use in Prism is as a first step in outlier detection. It is the baseline from which to determine if a residual is "too large" so the point should be declared an outlier.
