title: Statsmodel Z-test not working as intended (statsmodels.stats.weightstats.CompareMeans.ztest_ind)
body: <p>Everything is formatted like on the Statsmodels website, however somehow Spyder is returning this:</p>
  <blockquote>
  <p>TypeError: ztest_ind() got multiple values for argument 'alternative'</p>
  </blockquote>
  <p>My relevant input is this (data frame is working fine):</p>
  <p><code>ztest = statsmodels.stats.weightstats.CompareMeans.ztest_ind(df1['TOTAL'], df2['TOTAL'], alternative = 'two-sided', usevar = 'unequal', value = 0)</code></p>
  <p>I am following the formatting on this website: <a href="https://www.statsmodels.org/devel/generated/statsmodels.stats.weightstats.CompareMeans.ztest_ind.html" rel="nofollow noreferrer">https://www.statsmodels.org/devel/generated/statsmodels.stats.weightstats.CompareMeans.ztest_ind.html</a></p>
