**# x=yt****²/b**** Professor Para Bola, MA PhD, Whisky-McNightly Chair of Medical Statistics, University of Afpuddle Department of Applied Mathematics and Mathematical Statistic writes:**

Dr Norm Alkurve makes a valid "*academic*" point when he suggests that my statement "*assuming x=ab**²** + y, where y is a constant ... *" [see A Statistician writes #286.4+e, Wednesday 15 April 2020] is not technically correct. Rather he suggests "*for the record*", that "*y is not a constant but rather a function of x+yg**² / mc, where c is the constant*". Were things so simple!

What Dr Norm Alkurve does not make clear in his statement is that the statement "*y is not a constant but rather a function of x+yg**² / mc, where c is the constant*" is itself only valid under "*certain** abnormal temperatures and conditions*" and that at this time of year in all of the relevant parts of Dorset [even allowing for the somewhat unseasonably weather] and certainly in hospital conditions, y is *so close to being a* function of x/x and thus a proxy-constant that to all intents and purposes it is a constant. We can thus say with a probability level of 44% [e=2.3434334443] that, in practice, the assertion that "*y is not a constant but rather a function of x+yg**² / mc, where c is the constant*" is an unhelpful *modifier* and not a fun*damental** restatement or refutation of* the original proposal that *"**assuming x=ab**²** + y, where y is a constant ...". *After all, *where* y is a constant*, y is *a constant: a consistent, logical and, I would suggest, irrefutable statement *in and of itself*.

Where Dr Alkurve himself strays into error is in his - surprisingly lax - suggestion that y is *invariably* a function of x+yg² / mc. I believe it was in 1964 that the famous Culinary Bio-ethicist Professor Brian Thrupiece established the variability of the function x+yg² / mc, demonstrating to the satisfaction of most open minds [my own included - at a much later date of course] that plant-based lifeforms exhibited different characteristics and were subject to different statistical representations than animal-based forms. I believe that his discovery was a happy, though unsought, finding arising from his attempt to model the statistical likelihood of fluff becoming unstable under certain laboratory conditions: work undertaken as part of the then top-secret thrupiece*diet* project.

For the record, it is also the case that, *in **vitro*, the description xd/c [where c is a function of by*²*/g] approximates so closely to the modified function yc that to all intents and purposes we can say that the popular musical rhythm combo AC/DC need not be challenged - a statement as true today as it was when Marcus Tullius [having endlessly *sedet in tablino]* originally put II and II together and made IV.
