Not able to import EPs from excel as Sample weight for BF method

[AmaanAliK]

Hi guys,

I wanted to ask how I can best import the EPs from excel (its just one column) into the package as a sample weight for the BF method. It keeps giving me errors and I think its because Im unable to convert into the right format. My code is as below and thank you very much for the help as always!
dfEP = pd.read_excel(file_path, sheet_name='EPy') dfEP['Year'] = pd.to_datetime(dfEP['Year'], format='%Y%m') raa = tri sample_weight = dfEP cl.BornhuetterFerguson(apriori=0.95).fit( X=raa, sample_weight=sample_weight ).ibnr_.sum()

chainladder could really give more helpful error messages. That'd be a nice improvement,

Everything has to be a triangle object, including premium vectors:

sample_weight = cl.Triangle(dfEP, origin='Year', columns="the_column_name_for_ep")
