alpha.fun

Functions used by <code>sma</code> when 'robust = TRUE'.

internal

Methods for fitting bivariate lines in
allometry using the major axis (MA) or standardised major axis (SMA), and
for making inferences about such lines. The available methods of inference
include confidence intervals and one-sample tests for slope and elevation,
testing for a common slope or elevation amongst several allometric lines,
constructing a confidence interval for a common slope or elevation, and
testing for no shift along a common axis, amongst several samples.
