1. n. [Reservoir Characterization]
The variation in the values of a one-dimensional data set. There are a number of readily recognized, possible distributions known to statistics, each with mathematical definitions. Statisticians may endeavor to find whether a data set is a good fit to any of the recognized distributions. Some examples include:
  • bimodal
  • Boltzmann
  • chi-squared
  • general normal
  • Gaussian or standard normal (bell-shaped curve)
  • normal
  • Poisson
  • student's t
  • .
