虽然是很基础的东西，但是很少有参考书涉及到这一块，所以很多人都误解为EViews不能做分布图。全部是自己编程的，拿出来和大家分享学习。

标准正态分布

workfile u 8001

series x=-4+0.001*@trend

series y=@dnorm(x)

series z=@cnorm(x)

xyline x y z

Binomial 分布

workfile u 1001

series zero=0

series x=zero+0.01*@trend

series y=@dbinom(x,10,0.1)

series z=@cbinom(x,10,0.1)

scat x y z

T分布

workfile u 101

series p=0.001+0.00999*@trend

series x=-5+0.1*@trend

series y=@dtdist(x,100)

series z=@ctdist(x,100)

xyline x y z

Chi-square 分布

workfile u 101

series p=0.001+0.00999*@trend

series x=0.1*@trend

series y=@dchisq(x,1)

series z=@dchisq(x,10)

xyline x y z

F分布

workfile u 101
series x=0.1*@trend
series y=@dfdist(x,5,5)
series z=@dfdist(x,10,10)
xyline x y z
