```
DROP TABLE IF EXISTS example_data_output, example_data_output_summary;
SELECT madlib.correlation( 'example_data',
'example_data_output',
'temperature, humidity'
);
```
produces
```
INFO: ['temperature', 'humidity']
CONTEXT: PL/Python function "correlation"
-[ RECORD 1
]----------------------------------------------------------------
correlation | Summary for 'correlation' function
| Output table = example_data_output
| Producing correlation for columns: ['temperature', 'humidity']
| Total run time = ('example_data_output', 2,
0.2568531036376953)
```
which looks OK, but
```
DROP TABLE IF EXISTS example_data_output, example_data_output_summary;
SELECT madlib.covariance( 'example_data',
'example_data_output',
'temperature, humidity'
);
```
produces
```
INFO: ['temperature', 'humidity']
CONTEXT: PL/Python function "covariance"
-[ RECORD 1
]----------------------------------------------------------------
covariance | Summary for 'correlation' function
| Output table = example_data_output
| Producing correlation for columns: ['temperature', 'humidity']
| Total run time = ('example_data_output', 2,
0.27153897285461426)
```
but it should say `Summary for 'covariance' function`
(2)
Above output should list groups if grouping is used, currently it does not.
(3)
Is it intentional to print the INFO message out every time that the
correlation/covariance functions
is run?
