The capital sigma, ?, in statistics represents the summation of a set of numbers or values. It is commonly used to express the sum of a sequence of observations or the sum of a statistical function, such as the sum of squared residuals in regression analysis. The notation ? is derived from the Greek letter sigma, which is the equivalent of the letter "S" in the Roman alphabet. The use of ? in statistics is a convention that facilitates the concise representation of mathematical formulas and statistical operations.
