I have always liked the idea of a company that sits between me and all the other services I engage. Like I am a client of ZipZorp and they negotiate on my behalf rentals, travel, providers, utilities et al. ZipZorp provides value to me by using their size to negotiate better rates, conditions, offer legal protection and as you put it remain hyperinformed in a way that I cannot. I would pay for a service like that.


Not quite; the probability of n/2 successes in n trials is given as Binomial(n,p) not p^n. p^n is correct for a single sequence but there are many possible sequences that result half heads, half tails and so you have a factor of "N choose X" or the so called "Binomial Coefficient".

> (0.4)^20 × (0.6)^20

and I think you mean (0.4)^10 × (0.6)^10 or more generally p^x*(1-p)^n-x.


I'm talking about the whole sequence; you're talking about the number of heads (or) tails in the sequence.

The number of heads is a sufficient statistic, so we'll get the same likelihood ratios out, but the likelihood values themselves will be larger.

You could make a similar point about the original CrossValidated Normal(0, 1)^N example by summarizing the data with the mean and sum of squares.

This doesn't work if the data were Cauchy(0, 1)^N instead.


At least some of the rejects are crash tested.


The floor is open grating above a pool of water that is pumped to reclaim the solids. Further the paint is electrostatically charged as it comes off the bell applicator so it is attracted to the body like a balloon to the wall.


Thanks. Was wondering about electrostatic myself. Still wondering how the grate itself doesn't get stained due to the air flow.
