+## ChiSqTest
+
+Chi-square Test computes the statistics of independence of variables in a contingency table,
+e.g., p-value, and DOF(degree of freedom) for each input feature. The contingency table is
+constructed from the observed categorical values.
+
+### Input Columns
+
+| Param name  | Type   | Default      | Description                |
+|:------------|:-------|:-------------|:---------------------------|
+| featuresCol | Vector | `"features"` | The feature vector.        |

Review Comment:
   nit: could you remove `The` in the description to be consistent with existing docs?
   
   Same for other params.
