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.
So the Weibull density function has a rich variety of shapes, depending on the shape parameter, and has the classic unimodal shape when \(k \gt 1 \). In the special distribution simulator, select the Weibull distribution. Vary the shape parameter and note the shape of the probability density function.For selected values of the shape parameter, run the simulation 1000 times and compare the empirical density function to the probability density function.ary the shape parameter and note the shape of the distribution and probability density functions. For selected values of the parameter, compute the median and the first and third quartiles. \(Z \) has reliability function \(G^c \) given by \[ G^c(t) = \exp(-t^k), \quad t \in [0, \infty) \].
