INTERCEPT function

PRO

The INTERCEPT function in Jspreadsheet Formulas Pro is a handy tool that helps you find the point where a line crosses the y-axis, based on a series of x- and y-values. By using this function, you're essentially defining the line's equation, which is crucial in data analysis and forecasting. In other words, INTERCEPT allows you to predict the y-value when x equals zero, based on existing data points. This function is commonly used in statistical analysis and trend projections.

Documentation

Returns the y-axis intercept of a line defined by a set of x- and y-values.

Syntax

INTERCEPT(known_y's, known_x's)

Parameter	Description
`known_y's`	The array or range of y-values that define the line.
`known_x's`	The array or range of corresponding x-values to known_y's. If omitted, Jspreadsheet assumes a set of 1, 2, 3, ..., n.

Behavior

The INTERCEPT function in calculates the point where a line will intersect the y-axis by using existing x-values and y-values. Here's how it handles various cell types:

Empty cells: The INTERCEPT function ignores empty cells.
Text: This function does not accept text values. If any cell in the range contains text, the function returns a #VALUE! error.
Booleans: Boolean values are treated as numbers in the INTERCEPT function; TRUE as 1 and FALSE as 0.
Errors: If any cell in the range contains an error, the INTERCEPT function will return that same error.
Non-Numeric values: Non-numeric values in a cell will cause a #VALUE! error.

Common Errors

Error	Description
`#DIV/0!`	This error occurs if the standard deviation of the given x-values equals zero.
`#N/A`	This error is returned when the array or range of x-values and y-values are of different lengths.
`#VALUE!`	This error is returned when non-numeric values are included in the x-values or y-values or if text is present in the cells.

Best practices

Always ensure that the arrays or ranges of x-values and y-values are of the same length to avoid a #N/A error.

Make sure that your dataset does not contain text or non-numeric values as they will result in a #VALUE! error.

Be aware that INTERCEPT function does not check whether your data fits a linear model, it only computes according to the method of least squares. Therefore, ensure your data is suitable for a linear regression model before using this function.

Use error checking functions like ISNUMBER or IFERROR to handle possible errors before they occur.

Usage

A few examples using the INTERCEPT function.

INTERCEPT(B2:B7, A2:A7) returns the y-intercept of the linear regression line for the data in the range A2:B7  
INTERCEPT(C2:C6, D2:D6) returns the y-intercept of the linear regression line for the data in the range C2:D6
