HP Prime Graphing NW280AAABA manual STAT1A25A37,h n x σ, REGRSInput range,model, configuration

	For example if you specify "h n Σ
		x", the first column will
	contain row headers, the first row will be the number of items
	in the input data, the second the sum of the items and the third
	the mean of the data. If you do not specify a configuration
	string, a default string will be used.
	Notes:
	The STAT1 f function only updates the content of the
	destination cells when the cell that contains the formula is
	calculated. This means that if the spreadsheet view contains
	at the same time results and inputs, but not the cell that
	contains the call to the STAT1 function, updating the data will
	not update the results as the cell that contains STAT1 is not
	recalculated (since it is not visible).
	The format of cells that receive headers is changed to have
	Show " " set to false.
	The STAT1 function will overwrite the content of destination
	cells, potentially erasing data.
	Examples:
	STAT1(A25:A37)
	STAT1(A25:A37,”h n x σ”).
REGRS	Attempts to fit the input data to a specified function (default is
	linear).

REGRS(Input range,[model], ["configuration"])

•Input range: specifies the data source; for example A1:D8. It must contain an even number of columns. Each pair will be treated as a distinct set of datapoints.

•model: specifies the model to be used for the regression: 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
