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

This package provides methods of 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.
