STEYX(y,x)
- is set of dependent values.
- is the set of independent values.
is set of dependent values.
is the set of independent values.
Description
- This function gives the standard error of the regression, which also is known as the standard error of the estimate.
- It is calculates the standard error for the straight line of best fit through a supplied set of and values.
- The standard error for this line provides a measure of the error in the prediction of for an individual .
- The equation for the standard error of the predicted is: SQRT(1/(n-2)[summation (y-y(bar)^2-[summation (x-x(bar)(y-y(bar)]^2/summation(x-x(bar))^2] ,where x(bar) and y(bar) are the sample mean and .
- In is the array of the numeric dependent values and is the array of the independent values.
- The arguments can be be either numbers or names, array,constants or references that contain numbers.
- Suppose the array contains text,logical values or empty cells, like that values are not considered.
- This function will return the result as error when
is the array of the numeric dependent values and 1. Any one of the argument is nonnumeric. 2. x and y are empty or that have less than three data points. 3. x and y have a different number of data points.
Examples
1.y={6,8,10,13,15,5}
x={1,4,9,11,20,3}
STEYX(G1:G6,H1:H6)=1.4350701130 2.y={2,9,1,8,17} x={10,4,11,2,6} STEYX(A1:A5,B1:B5)=5.944184833375 3.y={1,2,4,5,8} x={10,4,7,5} STEYX(A1:A5,B1:B4)=NAN
