CDF formula is below:
F(x,λ) = 1 - e-λxF(5,0.333333333) = 1 - 2.718281828459(-0.333333333)(5)
F(5,0.333333333) = 1 - 2.718281828459-1.666666665
F(5,0.333333333) = 1 - 0.18887560315235
F(5,0.333333333) = 0.81112439684765
Calculate the mean (μ):
| μ = | 1 |
| λ |
| μ = | 1 |
| 0.333333333 |
μ = 3.000000003
Calculate the median:
| Median = | Ln(2) |
| λ |
| Median = | 0.69314718055995 |
| 0.333333333 |
Median = 2.0794415437593
Calculate the variance (σ2):
| σ2 = | 1 |
| λ2 |
| σ2 = | 1 |
| 0.3333333332 |
| σ2 = | 1 |
| 0.11111111088889 |
σ2 = 9.000000018
Calculate Standard Deviation which is the square root of variance denoted as σ
σ = √σ2σ = √9.000000018
σ = 3.000000003
Calculate entropy:
Entropy = 1 - Ln(λ)Entropy = 1 - Ln(0.333333333)
Entropy = 1 - -1.0986122896681
Entropy = 2.0986122896681
What is the Answer?
F(5,0.333333333) = 0.81112439684765
