This is a follow-up to an earlier post about CovarianceMatrix.

There are several ways in which Statistics:-CorrelationMatrix can be improved.

CorrelationMatrix shares some inefficiencies with CovarianceMatrix, by computing correlations between the n columns, pairwise. But in doing so it also computes...

Hi everybody,

 

I am doing the following:

If you could go to CH6 then Section 1 then Exercises. #30 is giving me trouble

:( plz&thx

It seems Maple's Sample command cannot handle self-defined distribution well. Check this:

I am in a college level physiology class, and have been assigned the task of deriving the Boltzman equation with Maple.  I have never used Maple before and find myself at a loss how to even start.  I've read through the tutorials and still am having difficulty using this program.  To define Boltzman equation, we are supposed to plot the Boltzman curve of force vs probability that channel is open.  Force is just equal to x, and probability that channel is open would be on the y axis and is defined as a/(a+b).  The second component of the equation involves t

given 4 points ex. (-3,4),(-1,3),(0,5),(1,6). how can I find two polynomial of degree5 passing throuh these 4 point. Is is also possible to fing more than two ? How do you know ?(what if you want to find polynomial of degree three thru these4 point, how you know how many there exist?) I just made up those point...

To enable page numbering, I am instructed to select Page Numbers fom the Format menu, however, there's no Page Number choice on the Format menu of my Maple 12 installation. What can I do?

Thanks, Paul

If I have a set of numbers,

1, 2, 3, 4, 5

for example, how do I compute their mean?

How do I compute their standard deviation?

I am trying to avoid explicitly recopying cutting and pasting

my data over and over again, such as

a:= (1 + 2 + 3 + 4 +5 )/ 5;

sdev: = sqrt( (a-1)^2 + (a-2)^2 etc.

My REAL question is: WHERE in Maple 11 Help is an example shown anywhere of an explicit finite data set of numbers, such as 1, 2, 3, 4,5, or a set of pairs of numbers (2,3), (4,5) etc 

Hey,

I really need to integrate this equation:

for my calc class and I looked it up on an integral calculator online, and got some gigantic answer with logs and arctans... if you could show me the steps for this I wud gr8ly appreciate it!!!

Hi, sorry to open a new thread but the last one just got a bit too messy.

mathbin.net/5767 - What I want to do.

mathbin.net/5850 - What I have tried to do so far.

 

Any help on this would be greatly appreciated.  Thanks

Hi everyone,

I've been tinkering with this problem for the past week but I'm suck :S!  I've tried google, mapleprimes, and the maple help file and nothing.

It's really a quite bizzare problem where I can use a procdure that I've defined... so long as I don't use it in a loop :S.

The procudure (called OVLM) takes 2 numbers as inputs and outputs an algebraic expression with 4 parameters as outputs.

------------------------
Example:
> OVLM(3,7);

Hi maplers!

Me and some friends have been wondering for quite some time now, about the possibilities based on the folowing calclation:

b,c:=1,2

equ:=a^2=b^2+c^2 (just a commun equation)

Now comes the problem, since i need maple as a tool for making reports and whatever comes in handy, i need to think at the visual stuff too(since my teachers want it, *SIGH*). Then is there a function that just inserts the varriables into the equation, so thre resualt would be something like this:

Calc( equ,'input')

 

ok, let me see if I can explain. If we run the below code we will get a matrix with nstock stock price, a matrix with returns, a

correlation matrix of returns and a plot of the nstock stock prices. (the code work I hace checked it by copy past)
 

Hi, I'm traying to maje a double integrate of P(A(t+Deltat),A(t)) , the first one in in untion of dA(t) and the second one is in fuction of dA(t+ DeltaT). How can I indicate in Maple Deltat?  Is it possible to integrate in function of A(t)?

All variables are constant, except A(t) and A(t + Deltat),
