Would you mind throwing out an example of these types of functions.
Looking at Wikipedia (http://en.wikipedia.org/wiki/Probit) its seems
like the Probit function is very similar to what I want.
Thanks

In general this kind of function is very easy to construct using sums of basic
sigmoidal functions. The logistic and probit functions are commonly used for
this.

Thanks I'll have a look at this. I should have mentioned that the actual values
on the graph aren't important rather I was showing an example of how the
function should behave.

Hi, assuming you have x and want to generate y, then maybe
- if x< 50, y = 150
- if x> 175, y = 60
- otherwise :
either y = (100/(e^((x -50)/75)^2)) + 50

- or maybe y =sin((x+5)/38)*42+105

I need some help with one of my boost functions. I would like the
function to look something like the following mockup below. Starts
off flat then there is a gradual decline, steep decline then
gradual decline and then back to flat.
Can some of you math guys please help :)
Thanks.
