"Probability distribution fitting or simply distribution fitting is the fitting of a probability distribution to a series of data concerning the repeated measurement of a variable phenomenon. The aim of distribution fitting is to predict the probability or to forecast the frequency of occurrence … See more The selection of the appropriate distribution depends on the presence or absence of symmetry of the data set with respect to the central tendency. Symmetrical distributions When the data are … See more It is customary to transform data logarithmically to fit symmetrical distributions (like the normal and logistic) to data obeying a distribution that is positively skewed … See more Some probability distributions, like the exponential, do not support data values (X) equal to or less than zero. Yet, when negative data are present, such distributions can still be used replacing X by Y=X-Xm, where Xm is the minimum value of X.
