The Kakeya conjecture comes from geometric measure theory and provides opportunities to demonstrate somewhat deep knowledge in that area, although the modern research towards that end falls more in harmonic analysis. That said, Kakeya sets and analogues are still a matter of active research in geometric measure theory.

WebDec 21, 2024 · To calculate expected value of a probability distribution in Python, we can define a simple function: import numpy as np def expected_value (values, weights): values = np.asarray(values) weights = np.asarray(weights) return (values * weights).sum() / weights.sum() The following example shows how to use this function in practice. WebOct 27, 2014 · If I have a random sample of size n from a Uniform(0,1) and I define the geometric mean as G can anyone give me insight in to how I can find the expected value of G, E[G]? Once I can get my head around this I would like to extend it to the expected value of powers of G. Any help would be appreciated.
WebJun 8, 2024 · Expected Value of a Geometric Random Variable. The probability of any discrete RV is the sum of the probability-weighted outcomes. In a Geometric RV, we already know how to calculate the probabilities. For example, P(X=1) is the probability of one success, therefore P(X=1)=p.
