What is the Laplace Transform of a Gaussian Distribution?

Click For Summary

Discussion Overview

The discussion revolves around finding a large table of Laplace transforms and specifically inquiring about the Laplace transform of a Gaussian (normal) distribution with mean m and standard deviation s, under the assumption that it equals zero for t<0.

Discussion Character

  • Homework-related
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant requests a large table of Laplace transforms in various formats and asks for the Laplace transform of a Gaussian distribution.
  • Another participant provides a link to a table of Laplace transforms but does not address the Gaussian transform question.
  • A different participant suggests creating a personal table as a means of practicing integration.
  • Some participants express frustration over the lack of direct answers to the original question about the size of the table needed.
  • One participant mentions that Schaum's book contains a large number of Laplace transforms, suggesting it as a resource.
  • Another participant provides a specific result related to the Laplace transform of the error function, indicating it may be useful for the Gaussian distribution question and offers to provide a derivation if needed.

Areas of Agreement / Disagreement

Participants generally do not agree on the definition of a "large" table of Laplace transforms, and there is no consensus on the Laplace transform of the Gaussian distribution itself, as the discussion remains unresolved on that specific point.

Contextual Notes

There are limitations regarding the assumptions made about the Gaussian distribution and the specific forms of the Laplace transforms discussed. Some participants rely on external sources for information, which may not fully address the original inquiry.

I need a large table of Laplace transforms, do you know any good ones? Format HTML, Pdf, Ps, Latex or Word (?)

Extra question: what is the Laplace transform of a Gaussian (normal distribution), with mean m and standard deviation s (assume equal to zero for t<0)?

why not make your own table? good integration practice hehe :wink: :-p
 
I also know how to use Google - but you do not answer my question,
maybe I should define "Large" as more than, say, 150 transforms.

I do not need to practice integration

:rolleyes:

I typed "large table laplace transforms" into Google. Check out this link. It has 129 Laplace transform formulas.

It was the second link that came up. The first was this thread. :smile:
 
Schaum's intro to Laplace transforms has like 300 laplace transforms listed on a big table.

If it helps, the LT of the error function [tex]\frac{2}{\pi^{\frac{1}{2}} }\int_0^t e^{-u^2} du[/tex] is [tex]\frac {1}{s(s+1)^{1/2}}[/tex]

And since you can always work with the N(0,1) distribution instead of the more general N(m, sigma^2) I think you'll find the aforementioned result useful. If you need the derivation of the Lt just ask.
