Higher income individuals can afford to pay higher dollar amounts in taxes. The least fair tax is the sales tax - specifically sales taxes levied on life's necessities, such as food purchased in grocery stores. There is large variation across the country in terms of state/local tax burdens on the poor.
The U.S. Air Force recognized the merit of Weibull's method and funded his research until 1975. Today, Weibull analysis is the leading method in the world for fitting and analyzing life data. Dorian Shainin introduced the author to statistical engineering at the Hartford Graduate Center (RPI) in the mid-fifties.
Depending on the values of the parameters, the Weibull distribution can be used to model a variety of life behaviors. We will now examine how the values of the shape parameter, , and the scale parameter, , affect such distribution characteristics as the shape of the curve, the reliability and the failure rate.ffects of the Shape Parameter, beta. The Weibull shape parameter, , is also known as the slope. This is because the value of is equal to the slope of the regressed line in a probability plot. Different values of the shape parameter can have marked effects on the behavior of the distribution.
