The function f_oneway_repeated in the hana_ml.algorithms.pal.stats module performs a one-way repeated measures analysis of variance, Mauchly's Test of Sphericity, and post hoc multiple comparison tests on a given DataFrame, returning statistics for each group, Mauchly test results, computed results, and multiple comparison results.
------
Here is a Python code template based on the provided documentation:

```python
from hana_ml.algorithms.pal.stats import f_oneway_repeated
from hana_ml import DataFrame

# Assuming that connection_context is already defined and a connection to HANA is established

# Define your data
data = {
    'ID': [1, 2, 3, 4, 5, 6, 7, 8],
    'MEASURE1': [8.0, 9.0, 6.0, 5.0, 8.0, 7.0, 10.0, 12.0],
    'MEASURE2': [7.0, 5.0, 2.0, 3.0, 4.0, 5.0, 2.0, 6.0],
    'MEASURE3': [1.0, 2.0, 3.0, 1.0, 5.0, 6.0, 7.0, 8.0],
    'MEASURE4': [6.0, 5.0, 8.0, 9.0, 8.0, 7.0, 2.0, 1.0]
}

# Create a DataFrame
df = DataFrame(connection_context, data)

# Perform the function
stats, mtest, anova, mult_comp = f_oneway_repeated(
    data=df,
    subject_id='ID',
    multcomp_method='bonferroni',
    significance_level=0.05,
    se_type='two-group')

# Print the results
print(stats.collect())
print(mtest.collect())
print(anova.collect())
print(mult_comp.collect())
```

Please replace the `connection_context` with your actual HANA connection context. The `data` dictionary should be replaced with your actual data.
