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.
Category
Statistical
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
orIFERROR
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
