524358 Create Normal Distribution(ND) plot and Cumulative ND Plots

The following job pertains to statistics. Those with statistical background can understand.

I need someone to use php to generate a normal distribution curve and a cumulative normal distribution. The mean shall be 100, and standard deviation will be 15. Example of this bell-shaped curve will be:

[url removed, login to view]

Here's link to examples of normal distribution curves, which are bell-shaped:

[Copy the whole chunk to your browser, and then visit the url directly, rather than click on it which can become broken]:

[url removed, login to view]+distribution+and+standard+deviation&hl=en&biw=1600&bih=809&prmd=imvns&tbm=isch&tbo=u&source=univ&sa=X&ei=GPB2TqfcDY_NrQeuw9zAAw&sqi=2&ved=0CFAQsAQ

When users enter a value for x into a textbox on screen and click "Ok", the curve's shaded area should change to reflect the shaded region from negative infinity to that value of x, say, 50 for example:

[url removed, login to view]

There is another region to be shown which is after x, ie from x to positive infinity, ie:

(is x is negative):

[url removed, login to view]

or

(if x is positive):

[url removed, login to view]

Here's link to an example of a cumulative normal distribution curve, which is also needed:

[url removed, login to view]

Here's link to how it is generated in MS EXcel, for instance, where commands already are available:

[url removed, login to view]

and [url removed, login to view]

I can do it in EXcel, but just not in php as I am not a php programmer.

If you manage to find these commands in php, then let me know, for I can advise what is mean, what is standard deviation, and what is x, to help you plot the normal distributions, the shaded areas inside, and the cumulative normal distribution I need.

I can provide you with the php required to generate your curves and shaded areas. I have an open source library which makes the job relatively simple. My degree contained a high percentage of statistics and probability Daha fazlası
