GRB~230812B is a bright and relatively nearby ($z =0.36$) long gamma-ray burst (GRB) that has generated significant interest in the community and has thus been observed over the entire electromagnetic spectrum. We report over 80 observations in X-ray

Asymptotic Normality of an M-estimator of regression function for truncated-censored data under alpha-mixing condition

Autor: Benseradj, Hassiba, Guessoum, Zohra

In this paper, we establish weak consistency and asymptotic normality of an M-estimator of the regression function for left truncated and right censored (LTRC) model, where it is assumed that the observations form a stationary alpha-mixing sequence.
