The Analysis Of Variance Is Not A Mathematical Theorem, But Rather A Convenient Method Of Arranging The Arithmetic.

The Best Causes Tend To Attract To Their Support The Worst Arguments, Which Seems To Be Equally True In The Intellectual And In The Moral Sense.

However, Perhaps The Main Point Is That You Are Under No Obligation To Analyse Variance Into Its Parts If It Does Not Come Apart Easily, And Its Unwillingness To Do So Naturally Indicates That One's Line Of Approach Is Not Very Fruitful.

I Believe That No One Who Is Familiar, Either With Mathematical Advances In Other Fields, Or With The Range Of Special Biological Conditions To Be Considered, Would Ever Conceive That Everything Could Be Summed Up In A Single Mathematical Formula, However Complex.

The So-called Co-efficient Of Heritability, Which I Regard As One Of Those Unfortunate Short-cuts, Which Have Often Emerged In Biometry For Lack Of A More Thorough Analysis Of The Data.
