quick linear fit with numpy

Parameters:

x – names of x variables in df or vector data, if y is None treated as target and fit against the index
y – names of y variables in df or vector data [optional]
w – names of weight variables in df or vector data [optional]
df – pandas DataFrame containing x,y,w data [optional]
groupby – If specified the linear fit is applied by group [optional]
do_print – whether to print steps to console
catch_error – whether to keep going in case of error [optional]
return_df – whether to return a DataFrame or Series [optional]
extrapolate – how many iteration to extrapolate [optional]

Returns:

if return_df is True: pandas DataFrame, else: pandas Series
