I am trying to estimate the cumulative distribution function from a probability distribution function

for this I am using the lambda function (code given below), but it gives some negative values at the end of series 

Dj_lin = lambda x: 1 - sp.integrate.quad(mypdf_lin, 0, x)[0]

here mypdf_lin is my pdf function

is there any other way to estimate the cdf from pdf ?

  • if it should return 0 at this point you could do ```np.clip``` – quester Sep 17 '19 at 07:44
