See section 6.4 on page 46 in CNAIM (2021). For calculating the location
factor for submarine cables please see the function
location_factor_sub(). Note the location factor for all other
cables are always equal to 1 hence the function will return a location
factor of 1 for other cables than submarine cables.

This function returns a combined factor using a maximum and
multiple increment (MMI) technique
(cf. CNAIM, 2021. page 54, section 6.7.2). The function can be used
to derive the health score factor for EHV and 132kV transformers.
For deriviation of the health score factor for all other assets see
health_score_excl_ehv_132kv_tf.
To derive the health score factor for EHV and 132kV transformers one needs
to use mmi() to derive the health score factor for
the main transformer and for the tapchanger respectively.
The constants factor_divider_1, factor_divider_2
and max_no_combined_factors are all available in the lookup
table 10 and 11 on page 57 and 58 in CNAIM (2021).
For an in dept description see also section 6.8 on page 57 in CNAIM (2021).
The mmi() can also be used in the derivation of observed and measured
condition factors for all assets, using measured and observed
input factors.
The constants factor_divider_1, factor_divider_2 and
max_no_combined_factors can be found in table 13 on page 63
(observed condition factors) and in table 15 on page 67
(measured condition factors).

This function uses transformer fault statistics data to train a Weibull model: Based on the environmental
factors determining a transformer's expected lifetime, the set of all data points is first partitioned into five parts.
Then a multilinear estimate for the expected lifetime of a transformer is trained for each part separately, and the
corresponding Weibull shape and scale parameters for the five parts are estimated. The function returns the shape and scale
parameters needed for the function predict_weibull_model().
