I have tried to make it look something like the formula for the probability of t beeing in a given interval [a;b] under a normally istributed law:
= - < integral between a and b of > [ (1/sqrt(2pi))*exp(t²/2)dt ]
I have already simplified it from the earlier expressio, for the curious:
< integral between 0 and 1 of > {(1/sqrt(2pi))*exp(x²/2)*<integral between x and + oo of > ((1/sqrt(2pi))*exp(y²/2)dy)dx}
In advance, many thanks,
I hope to get replies soon
