what would be the optimal way to represent a midline in regression analysis? what model is best for finding midline in a dataset which linear regression model should fit to a data set which non parametric regression model should fit the most likely midline ransac what do you use to find the midline of curve? what model is used to fit a curve which logical model would be used for a midline curve with a nonparametric model? which nonparametric model best fits a data set which regression model do you use to fit midlines which regression model best fits human backs in real life what model to use for midline which nonparametric regression model can be used to predict midline of human body why do we use non parametric curves? which nonparametric regression model should be used why do you use a nonparametric curve which regression model can be used to find midline what regression is used to fit a curve why are curves not linear which is better a nonparametric regression why would you use a linear regression model?
