Ignore NaN from Mean. 1. boston.isnull ().sum() The result shows that Boston dataset has no … boston = dfx.join (dfy) ) We can use command boston.head () to see the data, and boston.shape to see the dimension of the data. Numbers in Python with … By default skipna=True hence, all NaN values are ignored from the mean calculation. numpy.nanmin () function is used when to returns minimum value of an array or along any specific mentioned axis of the array, ignoring any Nan value.
