Webtruncated data, truncated regression is also used in two-part models (Cragg,1971) for censored type data: a binary (e.g., probit) regression model ﬁts the exceedance probability of the lower limit and a truncated regression model ﬁts the value given the lower limit is exceeded.

"WebIn this study, a robust online support vector regression algorithm based on a non-convex asymmetric loss function is developed to handle the regression of noisy dynamic data streams. Inspired by pinball loss, a truncated ε-insensitive pinball loss (TIPL) is proposed to solve the problems caused by heavy noise and outliers. " - Truncated regression in r
