14 Aug 2011 pearspdf Pearson system probability distributions Author: Pierce

Hey guys,
I appreciate all the comments etc.
But i don't have the time to fix these corrections. Its open source so feel free to change it and reuse it yourself.

Carsten Allefeld has made some modifications that fix the normalisation problem. Except in the case of the type 5 distribution.

The sizeOut error has also been fixed.

add this at line 164

p = p/sigma;

just after
p = pearson4pdf(X,m,nu,a,lambda);

it seems the the pdfs are off by this factor

% You need to normalise the histogram properly
[Y,X] = hist(pearsrnd(m{:},100000,1),100)
dX = diff(X)
% Forgot to include this line
dX = dX(1)
bar(X,Y/(sum(Y)*dX))
hold on;
plot(-6:0.01:6,pearspdf(-6:0.01:6,m{:}),'r')

m and m2 will be different. pearsrnd generates random numbers that follow the distribution.
if you generate more numbers the values will begin to match much better.
i.e.
m = {0,1,0,3};%Norm Distrib
[x,type, coefs] = pearsrnd(m{:},100000,1);
m2 = [mean(x) std(x) skewness(x) kurtosis(x)]

% better

m = {0,1,0,3};%Norm Distrib
[x,type, coefs] = pearsrnd(m{:},100000000000000,1);
m2 = [mean(x) std(x) skewness(x) kurtosis(x)]
% Won't have a enough memory
% m and m2 should be very close if not the same

% As you you generate more and more numbers, the error
% between m and m2 will become smaller and smaller

% You need to normalise the histogram properly
[Y,X] = hist(pearsrnd(m{:},100000,1),100)
dX = diff(X)
bar(X,Y/(sum(Y)*dX))
hold on;
plot(-6:0.01:6,pearspdf(-6:0.01:6,m{:}),'r')

Question:

Occasionally I get an error Undefined function or variable 'sizeOut'. I can't find this value or variable in the code. Can anyone help?
13 Oct 2010 pearspdf Pearson system probability distributions Author: Pierce Nazarevych, Oleg

See good code in R
http://cran.r-project.org/web/packages/PearsonDS/
02 Oct 2010 pearspdf Pearson system probability distributions Author: Pierce Nazarevych, Oleg

edit your file:

122: case 1
....
136: p = betapdf(X,m1+1,m2+1)/sigma;
137: p=p/55;

177: case 6
...
187: p = fpdf(X,nu1,nu2)/sigma;
188: p=p/3;

and

195: p = fpdf(X,nu1,nu2)/sigma;
196: p=p/3;

it is not correct, but plot norm PDF hold on Hist (ecdfhist)
30 Sep 2010 pearspdf Pearson system probability distributions Author: Pierce Nazarevych, Oleg

and not correct for Pearson Type I
coefs = [1.2197 0.30669 -0.07322]
