I noticed that the letter z is different from other font. Is there any special command for this?

  • It's just how a font realizes the italic z. Nothing special about z-score.

Times font in both cases. The difference is italic versus upright. Kerning is slightly different if employed as math versus italic.

With MathTime Professional 2 fonts from PCTeX, complete or lite version, reading the guide to pag. 7, you can use in math-mode the "swash" z, putting into \usepackage[.....,lite]{mtpro2} the option zswash.

This is the relative output.
