Continuous Uniform Desity Function-Cummulative Distribution

[PDEM200]

Hello,

Question about Continuous Uniform Desity Function-Cummulative Distribution on pg.43 /112 (last paragraph),

Is the Cummulative formula always: F(X) = [ X - a ] / [ b-a ]

Thank you

Hi Paul,

Yes, but technically any CDF is bounded by 0 and 1. So, if X < a, F(X) = 0 and if X>b, F(X) =1.

Also note the topics here are orange highlight, which means: maybe helpful but not really an 2008 AIM. Last year, the "important distributions" included binomial, Poisson, uniform and lognormal.

But Gujarati has different "important distributions" as his focus is inference: t-, chi^2 and F-distribution. So what i mean is, technically, there is no 2008 AIM devoted to the uniform distribution.

Understood. Thank you for the quick reply
