estimated values for an
input y-value. For the argument, input the value of y immediately before
the

function.
y
ˆ ...... Function for determining the y estimated value for an input x-
value. For the argument, input the value of x immediately before this
function.
For non-quadratic regression
a, b ...... regression coefficients
r ...... correlation coefficient
x
ˆ ...... Function for determining x estimated value for an input y-value.
For the argument, input the value of y immediately before this function.
y
ˆ
...... Function for determining the y estimated value for an input x-
value. For the argument, input the value of x immediately before this
function.
For an example of the operation to determine estimated values, see
