@rosefox bingo! and you’ve found *another* sampling bias inherent in iWatch.

@dakami @HolzmanTweed not sure we’re disagreeing. I agree that large N could be valuable, but bias needs to be addressed, w/eye to privacy.

@dakami @HolzmanTweed (2/2) Correcting for oversampling rich will likely require privacy invasion, especially for undersampled.

@dakami @HolzmanTweed (1/2) making N bigger does not address sampling bias.

@dakami @HolzmanTweed of course not, but this isn’t the promise of cardiac db for the masses. Still missing: privacy concerns & mass-uptake.

@erinbiba let me know what you find? I can imagine a story about that non-zero net pressure curve, but not sure it holds, uh, water.

@erinbiba Not just you. I have that sensation about 50% of the time. I wonder if the net cancelled pressure wave is non-zero (though flat)?

@dakami @HolzmanTweed not the watch, though. $350 is not a price for impulse buys unless you’re wealthy.

.@dakami @HolzmanTweed hugely problematic sampling bias means good news for big pharma: EXCELLENT sample of cardiac risk for the rich.

RT @thelancearthur: Oh god oh god, people on CalTrain all yelling at their wrists. Yay.
