发帖数: 34 | 2 In Bayesian econometrics, we need estimate the moments of functions of
interests, for example, the expecttation of f(a): E[f(a)|D], where
a is a random number and D is observed data.
E[f(a)|D]=Integrate[(f(a)*p(a|d)),{a}]. Where p(a|D) is posterior
density of a. Generally, we can not find
the closed form of the integration, so some numeriacl methods is neccessary.
The first method is Laplace's method. This method changes the problem
to a numerical derivative, which is much easier. However, this |

发帖数: 10 | 13 I generate Y data from Monte Carlo simulation. THen I plot Y data against X.
The curve is not a smooth line but jitters. I was wondering how to calculate
the area under the curve? Because the Y data jitters so much, usual numerical
method like simpson's ruke, Gaussian quadrar=ture seems not working. IT looks
like we nee dsome kind algorithm to soomth this data, then do inegration? |

发帖数: 12 | 15 yes, you need to approximate your curve with some smooth curve before yo
u do , for example quadratic functions (that's simpson's rule), but of c
ourse the accuracy might not be good enough, so you may use piecewise qu
adratic functions or in general consider spline functions. Another techn
ique called least squares fitting might also give a good smooth curve fo
r you to integrate using standard quadrature formulas.

发帖数: 74 | 47 Hello,
I wonder if anyone have experience using Nolan 1997 'Numerical calculation
of stable densities and distribution functions" formula to calculate stable
densities.
I have some problem with the results when beta is non-zero. If beta is zero,
my limiting case agree with normal density and Cauchy densities, although
there are some discontinuity when x to be around +-6 (far extreme cases).
When beta is non-zero, in other words distribution is skewed, somehow my
code could not generate sensible |

You can solve it using the sherman-morrison formula
which tells you how to invert A+u\otimes v.

for details of S-M formula and code for inversion of

by
f(r)= \int_0^\infty g(k) sinc(kr) dk, where sinc(x)=sin(x)/x, g(k)
is a tabulated function. Now I can certainly do the integral one by
one, but hoping to use FFT to improve efficience, I observed that this
can be rewritten as
f(r)=1/r \int_0^\infty g(k)/k dk, which is just the sine
transformation.
So, I used the program sinft given in numerical recipes to
do the calculation. However, it seems that the result is very
