Ultrasonic frequency-dependent attenuation (FDA) coefficients of the liver obtained from selected regions of interest within the liver were determined in 106 individuals, 40 cases presumed normal based on medical histories and 66 with malignant tumors (hepatocellular carcinoma [HCC] or metastatic li
Suppose our data {Xn} come from the model Xt = โ j = 0 cjZt-j, where {Zn} are i.i.d. with a symmetric distribution function which lies in the domain of normal attraction of a stable law with index โ (1; 2). Further we assume that cj = j d-1 L(j), where parameter d โ (0; 1 -1= ) and L is a normalized
