Identification of parameters of a combined piece-linear regression model

Subject of research: the problem estimating parameters a combined piecewise linear regression model.
 Purpose to apply apparatus Boolean programming identify its parameters. 
 Methods and objects object research is set indicators inventive activity in Russian Federation, methods are analysis mathematical programming.
 Main results an approach model by using method least modules described, which makes it possible reduce this problem. A Federation has been constructed, can be used various analytical predictive calculations. The output variable number patent applications, input volume gross domestic product, graduate students teaching staff.
