Formula Generator - LINEST function

The LINEST function is used to calculate various parameters of a linear trend using the least-squares method. It returns an array of values that represent the coefficients of the linear equation that best fits the given data points. The function takes the following arguments: - known_data_y: The array or range of dependent data points. - known_data_x (optional): The array or range of independent data points. If omitted, the function assumes a simple linear regression with the independent variable being the array [1, 2, 3, ...]. - calculate_b (optional): A logical value that determines whether to calculate the y-intercept (b) of the linear equation. If set to TRUE or omitted, the function calculates the y-intercept. If set to FALSE, the function assumes a y-intercept of 0. - verbose (optional): A logical value that determines whether to return additional statistical information. If set to TRUE, the function returns additional information such as the standard error and degrees of freedom. If set to FALSE or omitted, only the coefficients of the linear equation are returned.

LINEST formula syntax.

The LINEST function in Excel is used to calculate the statistics of a straight line that best fits a set of data points. It returns an array of values that represent the slope, y-intercept, and other statistical information about the line. The syntax for the LINEST function is as follows: LINEST(known_y's, [known_x's], [const], [stats]) - known_y's: This is a required argument that represents the array or range of dependent (y) variables. - known_x's: This is an optional argument that represents the array or range of independent (x) variables. If omitted, Excel assumes a simple regression with a single independent variable. - const: This is an optional argument that specifies whether to force the y-intercept to be zero. If set to TRUE, the y-intercept will be forced to zero. If set to FALSE or omitted, the y-intercept is calculated normally. - stats: This is an optional argument that specifies whether to return additional statistical information. If set to TRUE, additional statistics such as R-squared and standard errors are returned. If set to FALSE or omitted, only the coefficients of the line are returned. The LINEST function should be entered as an array formula, which means you need to press Ctrl+Shift+Enter after typing the formula instead of just pressing Enter. Note that the LINEST function can handle multiple independent variables by using a matrix of known_x's.

Use Cases & Examples In these use cases, we use the LINEST function to calculate the linear regression for a set of data points and determine the slope and y-intercept of the best-fit line.
