WebMartin Oritz, a purchasing manager of the True Taco fast food chain, was contacted by a salespersoa of a food service company. The salesperson pointed out that the higher breakage rate was common in the shipment of most taco shells. Martin was aware of this fact, and noted that the chain usually experienced a 10% to 15% breakage rate.

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 of the magnitude of the phenomenon … 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 Skewed distributions can be inverted (or mirrored) by replacing in the mathematical expression of the cumulative distribution function (F) by its complement: F'=1-F, obtaining the See more The option exists to use two different probability distributions, one for the lower data range, and one for the higher like for example the Laplace distribution. The ranges are separated by a break-point. The use of such composite (discontinuous) probability … See more The following techniques of distribution fitting exist: • Parametric methods, by which the parameters of … See more It is customary to transform data logarithmically to fit symmetrical distributions (like the normal and logistic) to data obeying a … See more Some probability distributions, like the exponential, do not support data values (X) equal to or less than zero.
