that may be, the conditional entropy of a symbol presented the many prior symbols produced. For the more normal case of a process that isn't necessarily stationary, the standard level is:
Primary framework of navigational CODASYL database product The introduction on the term database coincided with The supply of direct-accessibility storage (disks and drums) with the mid-nineteen sixties onwards.
