I explored data from several studies in the fileld of medicine. I found that distributions of many variables (eg. blood level of some substances) are right-skewed, often corresponding to log-normal distribution.
Is skewness of variable distriubtion a hint in investigation of its nature? Or maybe manner in which it depends on other variables? . . ================================================================= Instructions for joining and leaving this list, remarks about the problem of INAPPROPRIATE MESSAGES, and archives are available at: . http://jse.stat.ncsu.edu/ . =================================================================
