Reverse the exponential probability distribution

Emmanuel_Romeu

Hello,

I have a customer willing to calculate the reverse of exponential probability distribution in JMP through a formula column i.e. start from a probability density of the exponential distribution and find the data (which are times) based on the initial formula which is likely : Exp Density( :’ time (minutes) ’n, Scale ).

Thanks

Hi @Emmanuel_Romeu ,

I'm not sure I understand what your customer wants to do, but how about using the minimise function?

intial = 0.1;
minFun = Minimize(
	(:y - Exp Density( intial, 0.1 )) ^ 2,
	{intial},
	<<UseNumericDeriv( "true" )
);
Eval( intial );

I hope it helps.

Yuichi
