Example 4: Simulate 100 observations on a normal random variable N( µ =80, σ
Ensure that is set to radian measure and type:
MODES
MAKELIST(80+ 50*( (-2*LN(RANDOM))*sin(2*RANDOM)),X,1,100,1) C2
Example 5: Simulate 50 observations on an exponential distribution with mean = 2.
In the HOME view type:
As an illustration, the result of this particular simulation is shown
graphically on the right. Its mean turned out to be 2.067 (3 decimal
places.). Yours will be different of course - after all, that's the point of
using random numbers!
