So I asked my self: Self, is it possible to tune an extended range Critical Power Model to act like WKO4 ?
looks like a pretty good start from the training set.
hold up those numbers look funny what data did you use to train the model ?
wait so let me see that again…
hmmm ok well what about the r^2 and residuals
r^2 of 1 but then what’s with the residuals not being perfect ?
probably because digitizing plots isn’t perfect…
and its persumably not the same model
but Cog showed that FRC does not equal W’ and therefore needed a new term
same with FTP so this can’t possible by a Critical Power Class model can it?
a Critical Power class model can’t behave like something that isn’t a Critical Power class model?
wait why are there two lines?
ok fine its a Critical Power class model, but but but that’s just the training set what if your exponentials interact with the Flux capacitor, remember the map is not the territory!
anybody can tune something to match a training set that doesn’t mean anything!
you can’t show anythig without a test set, do you have a test set!?
yup sure do r^2 better than 0.96 despite the restricted range.
are you really using 15 years of Coggan’s personal PD data to make a point on your blog?
yeah a bit tacky I know but its what I had
wait did you somehow steal the WKO4 model already?
nope just tuned a Critical Power class model to act like it.
so then does it still screw up like WKO4 when dealing with submaximal data?
yup it sure does. suprisingly not as often as WKO4 did on Coggan’s data set but here’s one clear example were it does.
so what do you do about that?
1. clean out the submaximal data and re-run it
2. use a brute force algorithm to rerun the model with an array of fixed CP values then select the best statistical fit (or range of fits) that doesn’t violate the model assumptions.
ps Andy, yes I did block you on twitter. I can’t deal with the endless repetition of non-informative cliches. And its been a while since you taught me anything. I do apreciate some of the early stuff it was quite helpful but lately its gotten old. Cheers bud.
