Input/Output: Level 1/Argument 1 Level 1/Item 1 See also: object CR, DELAY, OLDPRT, PRLCD, PRST, PRSTC, PRVAR object PREDV Type: Command Description: Predicted y-Value Command: Returns the predicted dependent-variable value ydependent, based on the independent-variable value xindependent, the currently selected statistical model, and the current regression coefficients in the reserved variable PAR. PREDV Input/Output: Level 1/Argument 1 Level 1/Item 1 xindependent ydependent See also: PREDY Command PREDX Type: 3-126 Full Command and Function Reference Description: Predicted x-Value Command: Returns the predicted independent-variable value xindependent, based on the dependent-variable value ydependent, the currently selected statistical model, and the current regression coefficients in the reserved variable PAR. The value is predicted using the regression coefficients most recently computed with LR and stored in the reserved variable PAR. For the linear statistical model, the equation used is this: ydependent = (mxindependent) + b where m is the slope (the third element in PAR) and b is the intercept (the fourth element in PAR). For the other statistical models, the equations used by PREDX are listed in the LR entry. If PREDX is executed without having previously generated regression coefficients in PAR, a default value of zero is used for both regression coefficients, and an error results.

The value is predicted using the regression coefficients most recently computed with LR and stored in the reserved variable PAR. For the linear statistical model, the equation used is this: ydependent = (mxindependent) + b where m is the slope (the third element in PAR) and b is the intercept (the fourth element in PAR). For the other statistical models, the equations used by PREDY are listed in the LR entry. If PREDY is executed without having previously generated regression coefficients in PAR, a default value of zero is used for both regression coefficientsin this case PREDY will return 0 for statistical models LINFIT and LOGFIT, and error for statistical models EXPFIT and PWRFIT. PREDY Input/Output: Level 1/Argument 1 Level 1/Item 1 xindependent ydependent See also: COL, CORR, COV, EXPFIT, LINE, LINFIT, LOGFIT, LR, PREDX, PWRFIT, XCOL, YCOL Return difference between values of a function at two specified values of the current variable. PREVAL CAS: PREVPRIME CAS: Given an integer, find the closest prime number smaller than the integer. Full Command and Function Reference 3-127 PRLCD Type: Command Description: Print LCD Command: Prints a pixel-by-pixel image of the current display (excluding the annunciators). The width of the printed image of characters in the display is narrower using PRLCD than using a print command such as PR1. The difference results from the spacing between characters. On the display there is a single blank column between characters, and PRLCD prints this spacing. Print commands such as PR1 print two blank columns between adjacent characters. PRLCD Flags: I/O Device (-33), Printing Device (-34), Double-spaced Printing (-37), Linefeed (-38). If flag -34 is set, flag -33 must be clear. Input/Output: None See also: CR, DELAY, OLDPRT, PRST, PRSTC, PRVAR, PR1 PROMPT Type: Command Description: Prompt Command: Displays the contents of "prompt" in the status area, and halts program execution. Access: !LIN LPROMPT Input/Output: Level 1/Argument 1 Level 1/Item 1 See also: "prompt" CONT, DISP, FREEZE, HALT, INFORM, INPUT, MSGBOX PROMPTSTO Type: Command Description: Prompt Command: Creates a variable with the name supplied as an argument, prompts for a value, and stores the value you enter in the variable. Access: . . . PROMPTSTO Input/Output: Level 1/Argument 1 Level 1/Item 1 "global" See also: PROMPT, STO PROOT Type: Command Description: Polynomial Roots Command: Returns all roots of an n-degree polynomial having real or complex coefficients. [. . . ] key 22. 21 is MODE with the left-shift key held down. . . also called LS&MODE. AMORT (79 MENU) This means that AMORT is not in any keyboard menu, but you can find it in numbered menu 79 (type 79 MENU to go to that menu). QUOT (POLYNOMIAL NXT; ARITH POLY PREV) This means that QUOT is in the POLYNOMIAL menu, a special menu which is not a numbered menu, nor on the keyboard, but is seen by executing the programmable command POLYNOMIAL. QUOT can also be found in the ARITH POLY PREV menu. The Command Menu-Path Table I - 1 CATALOG: 812 COMMANDS (802 are shown by CAT) -------------------------------------------! [. . . ]
