<li><p><code><a href="reference/np.svar.html">np.svariso.corr()</a></code> computes a bias-corrected nonparametric semivariogram estimate using an iterative algorithm similar to that described in Fernandez-Casal and Francisco-Fernandez (2014). This procedure tries to correct the bias due to the direct
