During World War II, the Navy also briefly maintained a rating of Specialist, similar to the rank in the United States Army.
In mathematics and statistics, a stationary process (or strict(ly) stationary process or strong(ly) stationary process) is a stochastic process whose joint probability distribution does not change when shifted in time.
Not to be confused with a fixed point where x = f (x) . This article is about stationary points or critical points of a real-valued function of one real variable. For the general notion, see Critical point (mathematics) .f the function is twice differentiable, the stationary points that are not turning points are horizontal inflection points. For example the function has a stationary point at x=0, which is also an inflection point, but is not a turning point.
