Dear all,
I am just trying to replicate this MATLAB example of the Gamma
probability density function:
http://de.mathworks.com/help/stats/gampdf.html?requestedDomain=www.mathworks.com#zmw57dd0e292788
According to this, Matlab yields for shape=scale=1 and a x-vector seq(1,5) :
y = 0.3679 0.3033 0.2388 0.1947 0.1637
but with gretl I obtain correctly (just checked it with some statistical
tables)
y (1 x 5)
0.36788 0.13534 0.049787 0.018316 0.0067379
<hansl>
mu = seq(1,5)
y = pdf(g,1,1,mu)
</hansl>
Just out of curiosity: What is Matlab doing? (the same results are
obtained by Octave)
Artur
