DnE(Distribution and Equation)
Description
The package involves two kinds of functions. One is to
solve cubic and quartic equations. The other is to analyse the
distribution of a set of given data. The function Cubic and
Quart are for solving equations. The function which has the
form as "is.xxdistribution" is for analysing whether the data
obeys the xxdistrbution. If you don not know which distribution
to judge, use function is.dt.
