\betaThe Greek letter \beta is commonly used in mathematics and science to represent a variety of concepts, including coefficients, angles, and beta particles in physics. It is the second letter of the Greek alphabet and is often used in statistics to denote a type II error or the beta coefficient in regression analysis.
Linear regression equation where \beta_0 is the intercept and \beta_1 is the slope.
y = \beta_0 + \beta_1 xSigmoid function in logistic regression.
\beta = \frac{1}{1 + e^{-x}}Beta plus decay in nuclear physics, where a proton is converted into a neutron.
\beta^+ \text{ decay}
