Seldom to ask question after retired math hobby Just waiting for beauty who born in 1994 And waited for her email to mavio@protonmail.com What is the difference in ownership among different universe?

i get it. Thank you.

it would take many steps. Anyway, i can do it

even if changed to Variance(X) = StandardDeviation(A)^2

the graph of beta is still a vertical straight and far apart from distribution of real data,

why?

a can be any function

or

you can try a := t -> t^2;

a can be any function

or

you can try a := t -> t^2;

## @marc005 i discover sample size = 1...

i discover sample size = 10, it return the same result

if size = 20 always return reject

and size = 10 always return accept

what do it mean ?

does it mean that i should not buy or sell this time?

i discover it sometimes return reject, or sometimes return accept

does it suggest that not to do anything if reject now? or only reflect past situation?

if only reflect past situation, any books or paper written a hypothesis testing can reflect in coming future?

## @marc005 moreover, what is signafic...

moreover, what is signaficant testing for ? when i get false from this testing for real equity data, what do it reject?

if it mean that there is significant difference between the data sets,

what do "significant difference between the data sets" mean?

anything that failed to do when there is significant difference between the data sets?

## @marc005 my goal is to replace exp(...

my goal is to replace exp(-r*x) with FF2 where 0<=p<=1 and 0 <= q <=1

when you plot FF2, you will see it is like exp(-x) between 0 and 1, when n is larger, converge faster

through the method of making Poisson, and Gamma Function

but i failed at step

tm := simplify(int(expand(1/(rho*sqrt(2*Pi*g))*exp(-((X-theta*g)^2)/(2*g*rho^2))*MartinDensity),g=0..infinity));

Could you make this derive steps success?

P := p*z+q*z^2;
FF2 := P/(1+P);
FF2 := subs(z=T, (1/(diff(FF2, z)/(subs(z=0,diff(FF2, z)))))^r); # this step invent by me to micmic exp(x)

After find P(n=1 | r,M), P(n=2 | r,M), P(n=3 | r,M)

with(Statistics):
MartinPoisson := (p/((p+2*q*T)/(1+p*T+q*T^2)-(p*T+q*T^2)*(p+2*q*T)/(1+p*T+q*T^2)^2))^r*r^2*T^n/factorial(n);
