Figure 1From: Detecting outliers when fitting data with nonlinear regression – a new method based on robust nonlinear regression and the false discovery rateThe Lorentzian distribution. The graph shows the t probability distribution for 1, 4, 10 and infinite degrees of freedom. The distribution with 1 df is also known as the Lorentzian or Cauchy distribution. Our robust curve fitting method assumes that scatter follows this distribution.Back to article page
