The emphasis here is on going beyond what is obviously and readily available, with pointers to minor and major trickery and various user-written commands. For plotting histogram-like display...

Both official Stata commands and user-written programs are available. After a stacking trick for binary responses is explained, bar charts and related displays for cross-tabulations are discussed in detail. Tips and tricks are introduced for plotting cum...

متن کاملPermuting operations on strings and their relation to prime numbers
Some length-preserving operations on strings only permute the symbol positions in strings; such an operation X gives rise to a family {Xn}n≥2 of similar permutations. We investigate the structure and the order of the cyclic group generated by Xn. We call an integer n X-prime if Xn consists of a single cycle of length n (n ≥ 2). Then we show some properties of these X-primes, particularly, how X...
