Ti-Nspire CX : Gamma and Beta Distribution

Solve Gamma and Beta Distribution problems using the Ti-Nspire CX’s Statistics Made Easy APP (download : https://www.tinspireapps.com/?a=SPME )

  1. Easily compute Gamma values. You may enter integers , fractions or decimals (which uses the Lanczos Approximation). See below.

Similarly, Beta values can be found (which uses the Gamma Function):

After all this prep work, you can then find the Mean and Variance of the Beta Distribution AND evaluate the Beta CDF after entering the x-bounds, Alpha and Beta as shown below:

Gamma Distribution can be done similarly. See below.

Enter x, Alpha and Beta to find Gamma PDF:

And the Gamma CDF is evaluated , see below:
