On Performance of Two-Parameter Gompertz-Based X¯ Control Charts
Journal of Probability and Statistics, 2020 In this paper, two methods of control chart were proposed to monitor the process based on the two-parameter Gompertz distribution. The proposed methods are the Gompertz Shewhart approach and Gompertz skewness correction method.

Finding the Growth Rate of a Tumor
Undergraduate Journal of Mathematical Modeling: One + Two, 2020 The Gompertz method is used to analyze the growing glioblastoma data and estimate how accurate the results of growth over time are. The Gompertz curve is expressed as V(t) = αe-βe-γt. The data from the tumor is graphed in Excel along with the values from
