When only one variable is used, the “ known_ys” and the “ known_xs” can be the ranges of any shape with equal dimensions. The range of “ known_xs” can have one or more sets of variables.
stats: It represents a logical value ( TRUE/FALSE) specifying whether to return additional regression statistics.const: It represents a logical value ( TRUE/FALSE) specifying whether to force the constant ‘ b’ to be equal to ‘ 0’.known_xs: It indicates the set of x-values already known in the relationship “ y = mx + b”.known_ys: It indicates the set of y-values already known in the relationship “ y = mx + b”.Similarly, if the range of “ known_ys” is in a single row, each row of “ known_xs” is interpreted as a different variable. Note: If the range of “ known_ys” is in a single column, each column of “ known_xs” is interpreted as a separate variable. The arguments of the LINEST function in Excel formula are, The Syntax of the LINEST function in Excel formula is, Once the values of m and b are known, we can calculate any point on the line by putting the ‘ y’ or ‘ x’ value into the equation. The equation of a straight line is “ y = mx + b”.Y-intercept (b): The ‘ b’ representing the y-intercept of a line is the value of y at the point where the line crosses the y-axis.For a line with two points (x1, y1) and (x2, y2) the slope is calculated as m=(y2 – y1)/(x2 – x1). Slope (m): The ‘ m’ represents the slope of a line.We can describe a straight line with slope and y-intercept:.The value of ‘ y’ predicted by the regression equation may not be valid if they are outside the range of the ‘ y’ values used to determine the equation.Separator characters may vary depending on native regional settings. On entering an array constant “ known_xs” argument, use commas to separate the values in the same row and semicolons to separate the rows.y-intercept : =INDEX(LINEST(known_y’s,known_x’s),2).slope : =INDEX(LINEST (known_y’s,known_x’s),1).The ‘y’-intercept values can directly be calculated by using an independent x-variable, slope, and also with the following formulas:.The LINEST Excel function helps us to calculate the regression with the help of the known values as input.
