1-VAR	Analyzes data from 1 set of data with 1
	measured variable: x.
LIN	Analyzes paired data with 2 measured
	variables: x, the independent variable,
	and y, the dependent variable. Yields
	regression equation in the form y=a+bx.
LN	Analyzes paired data with 2 measured
	variables. Yields regression equation in
	the form y=a+b ln x.
EXP	Analyzes paired data with 2 measured
	variables. Yields regression equation in
	the form y=abx.
PWR	Analyzes paired data with 2 measured
	variables. Yields regression equation in
	the form y=axb.
CLRDATA	Clears data values without exiting STAT
	mode.

You can enter up to 42 points or data pairs.

When using the LN regression, you do not need to find the natural logarithms of the numbers. Enter the data directly, and the TI-36X ümakes the transformation. Similarly, when you want to make a prediction with the LN regression equation, you enter the value of x directly (and not ln x), and the calculator returns the predicted value of y (and not ln y).
