Tweaking Exponential Distribution to Estimate the Chance for More Survival Time if a Cancerous Kidney is Removed

Patients with a malignant tumor in the kidney (recognized as hypernephroma in medical practice) are treated by what is known as nephrectomy (that is a surgical removal of the kidney) in addition to a combionation of chemotherapy and immunotherapy for the sake of more survival time. This articles develops and demonstrates a statistical methodology to assess the statistical significance of an estimated chance for more survival time by tweaking the exponential distribution in a novel manner. This methodology is useful for the surgeons as much as to the patients who plan to undergo kidney removal.
