Probability distribution curve
• The Beta distribution on [0,1], a family of two-parameter distributions with one mode, of which the uniform distribution is a special case, and which is useful in estimating success probabilities. • The arcsine distribution on [a,b], which is a special case of the Beta distribution if α = β = 1/2, a = 0, and b = 1.

Webb2 okt. 2024 · Probability distribution curves can help us understand how to gauge a stock’s risk and expected value. When we invest in a company’s shares, we are making a long-term bet that the share price will rise over time. But in investing, we never deal in absolutes but rather a range of probable outcomes.
