Program Lines: (In RPN mode) Description ! Stores b in B. Displays value. P Calculates coefficient m. ! Stores m in M. Displays value. Checksum and length: 9CC9 36 Defines the beginning of the estimation (projection) loop. 1L2 & ! & Displays, prompts for, and, if changed, stores x-value in X. Calls subroutine to compute yˆ . Stores yˆ -value in Y. Displays, prompts for, and, if changed, stores y-value in Y. & & !- L & %1L2 & ! % Adjusts index value to address the appropriate subroutine. Calls subroutine to compute xˆ . Stores xˆ in X for next loop. Loops for another estimate. Checksum and length: 9B34 42 This subroutine calculates yˆ for the straight-line model. Calculates yˆ = MX + B. ! Returns to the calling routine. Checksum and length: F321 15 This subroutine calculates xˆ for the straight-line model. !. L Restores index value to its original value. & . Calculates xˆ =(Y - B) ÷ M. ! Returns to the calling routine. Checksum and length: 65AB 18 This subroutine calculates yˆ for the logarithmic model. Statistics Programs 16-5
