WebAug 28, 2014 · Create a new series with the sorted values as index and the cumulative distribution as values: cum_dist = np.linspace (0.,1.,len (ser)) ser_cdf = pd.Series (cum_dist, index=ser) Finally, plot the function as … Web[f,xi] = ksdensity(x) returns a probability density estimate, f, for the sample data in the vector or two-column matrix x. The estimate is based on a normal kernel function, and is evaluated at equally-spaced points, xi, that cover the range of the data in x.ksdensity estimates the density at 100 points for univariate data, or 900 points for bivariate data. how can a psychologist help
