I study psychology and economics with a very quantitative approach to each. I specialised on statistical methods, quantitative diagnostics, portfoio analysis and econometrics. Furthermore I am interested (and above that theoretically and empirlcally involved) in poker, chess and performing arts.

These are questions asked by afeddersen

E.g. I want to modify the Binomial distribution in a way, that k is not the number of successes, but the outcome.

Let's assume each success wins $100, while a failure results in $0.

My thought was to substitute k for k/100, but that produces an error message.

Can anyone tell me, how to implement that in Maple?

 

Thanks a lot.

There was an interesting question from Christopher2222:

Maple keeps changing the variable xi to the greek letter

Now I need a solution for a specific application, Here is the code:

with(Statistics):

L:=[Normal, Beta, Gamma]:

for i to 3 do
f[i]:=RandomVariable(L[i](4,2):
end do:

This will work for L[1], but not for L[2] and L[3]...

Let's say I define L1..L5 and M1..M5 respectively

for i to 5 do:
L[i]:=(-i^2+6*i);
end do;

for i to 5 do:
M[i]:=(-i^3+18*i);
end do;

Now I want to find out, whether the maxima of the two sequences L1..L5 and M1..M5 have the same subscript.
So I need a kind of proc that outputs 'true', if subscript(max(L1..L5))=subscript(max(M1..M5)), 'false' for subscript(max(L1..L5))<>subscript(max(M1..M5)) and 'FAIL' otherwise.

Does anyone...

I tried the following:

a:=1:

b:=2:

c:=-1:

L:=[a,b,c]:

M:=max(L);

 

However Maple outputs M:=2, but I want Maple to tell me the corresponding assignment 'b' of the maximum value of L, or at least 'L[2]'.

Is this possible and if so, how?

Thanks for answering.

I tried the following:

utility:=[CARA,CRRA,DARA]:

DARA1:=alpha+beta*x:

eval(utility[3]||1,[alpha=1,beta=2]);

 

Unfortnuately Mape ouputs: utility[3]||1

How can I get Maple to recognize the expression behind utility[3]||1?

Thanks for helping.
