com.ci

Estimated variance of the common slope.

varb

Critical value to be used in confidence interval calculation.

crit

Variances and covariances of each group.

Variance of fitted axis scores, for each group.

Variance of fitted residuals, for each group.

method

Error variance ration (implied by choice of method.

lambda

Residual degrees of freedom, for each group.

res.df

A vector of "robust factors" for each group, default value 1. Variance estimates are rescaled by this factor when using robust inference.

r.factor

Calculates a confidence inteval for a common slope (called by slope.com)

 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.
