HP Prime Graphing NW280AAABA manual PredYmode, x, parameters, PredXmode, y, parameters

PredY	Returns the predicted Y for a given x.
	PredY(mode, x, parameters)
	• Mode governs the regression model used:
	1 y= sl*x+int
	2 y= sl*ln(x)+int
	3 y= int*exp(sl*x)
	4 y= int*x^sl
	5 y= int*sl^x
	6 y= sl/x+int
	7 y= L/(1 + a*exp(b*x))
	8 y= a*sin(b*x+c)+d
	9 y= cx^2+bx+a
	10 y= dx^3+cx^2+bx+a
	11 y= ex^4+dx^3+cx^2+bx+a
	• Parameters is either one argument (a list of the
	coefficients of the regression line), or the n coefficients
	one after another.
PredX	Returns the predicted x for a given y.
	PredX(mode, y, parameters)
	• Mode governs the regression model used:
	1 y= sl*x+int
	2 y= sl*ln(x)+int
	3 y= int*exp(sl*x)
	4 y= int*x^sl
	5 y= int*sl^x
	6 y= sl/x+int
	7 y= L/(1 + a*exp(b*x))
	8 y= a*sin(b*x+c)+d
	9 y= cx^2+bx+a
	10 y= dx^3+cx^2+bx+a
	11 y= ex^4+dx^3+cx^2+bx+a
	• Parameters is either one argument (a list of the
	coefficients of the regression line), or the n coefficients
	one after another.
