 observations of the dependent variable in the region 

 with high variances, and the analysis will be overly 

 sensitive to chance events or bias affecting observa-

Length and weight relationships in fishes are of-

 inter-specific comparisons. Although many data are 

 available on weight at length relationships of fishes 

 from New Guinea (Showers, 1993) and New Cale-
