The available methods of\ninference include confidence intervals and one-sample tests for\nslope and elevation, testing for a common slope or elevation\namongst several allometric lines, constructing a confidence\ninterval for a common slope or elevation, and testing for no\nshift along a common axis, amongst several samples.
