ShdN
Draws the normal density function specified by mean m and standard deviation s
and shades the area between lowerbound and upperbound. The defaults are m =0
and s =1.
lowerbound upperbound[
ShdN( ,
Shdt
Draws the density function for the Student-t distribution specified by df (degrees
of freedom) and shades the area between lowerbound and upperbound.
