Exponential Distribution for the Probability Distribution Calculator
- Density Function
- The exponential distribution has the probability density function:
f(x) = le(-lx)
0 <= x < ∞, l > 0
where
- Distribution Function
- The cumulative distribution function (the term was first introduced by Wilks, 1943) for the Exponential distribution is:
0, x <= 0
F(x) =
1-e(-lx), x>0
- Exp
- This field displays the current variate value for the Exponential distribution. When you edit this value (either manually or with the microscrolls), Statistica computes the associated p-value for the specified scale parameter.
- p
- This field displays the p-value computed from the specified variate value and scale parameter or you can enter a desired p-value (either manually or edit the existing value with the microscrolls) and compute the critical value of the distribution for the specified parameter.
- Lambda
- Specify here the scale parameter of the distribution, l. If this parameter is changed, then the p-value will be recomputed based on the respective variate value.
