The logistic function is a common sigmoid curve often used in statistics, biology, and machine learning to model growth processes, probabilities, and binary outcomes. It is defined mathematically by the formula: \\\[ f(x) = \\frac\{L\}\{1 + e^\{-k(x - x_0)\}\} \\\] where: - \\(f(x)\\) is the output of the logistic function.
