NettetTo estimate a value beyond the data shown, extend the graph scale and line of best fit to include the desired point, and then estimate the value of the other coordinate. The equation for a line of best fit is: y=m (x)+b y = m(x)+b, where (x,y) (x,y) represents … NettetIn statistics, ordinal regression, also called ordinal classification, is a type of regression analysis used for predicting an ordinal variable, i.e. a variable whose value exists on an arbitrary scale where only the relative ordering between different values is significant.It can be considered an intermediate problem between regression and classification.
