A bar graph ranking the impact of various inputs of a model on a specific output. The classical tornado chart is obtained by fixing all but one input at some base value and letting the one input vary from its minimum to maximum. A similar graph is used in Monte Carlo simulation software, in which the bar widths represent either rank correlation coefficients or stepwise linear regression coefficients.
