The food pellets also have color additives that help give the farm raised salmon the nice pinkish color weâre all accustomed to. Otherwise, theyâd be a dullish grey color*. *Wild salmon, by contrast, obtain their pink hue from their natural environment by feasting on a diet of krill, which eats red algae. 7.
Generate random numbers with a given distribution. The rand function in MATLAB returns uniformly distributed pseudorandom values from the open interval (0, 1), but we often need random numbers of other kind of distributions. A great article written by John S. Denker explains a method of generating random numbers with arbitrary distribution.
I want to start a series on using Stataâs random-number function. Stata in fact has ten random-number functions: runiform() generates rectangularly (uniformly) distributed random number over [0,1). rbeta(a, b) generates beta-distribution beta(a, b) random numbers.
