what's the difference between CostLinear and CostCLinear ?

• CostLinear assumes a piecewise linear time series (without continuity at the change points).
• CostClinear assumes a piecewise linear time series WITH continuity at the change points (the C is for continuous).

- Thanks for for the quick response ！Below are some of my understandings, and I'm not sure if they are correct~

1. CostLinear : It applies to situations where the relationship between the yt ( observed dependant variable) and the xt (covariate vector), like the sales and GDP per capita、number of branch ... ( I understand it as feature )

2. CostClinear : It seems to be related to the slope, but I can't figure it out why there is a - 1 and b - 1
