The estimate of y for a given x (estimate y´) and the estimate
of x for a given y (estimate x´) can also be found. When there
are two x values, the COMP symbol will appear. Press @ to
switch between x values.
Exponential regression, logarithmic regression, power regression, and inverse regression calculations
Section 햲 and 햳 results, except for coefficients c.
The estimate of y for a given x (estimate y´) and the estimate
of x for a given y (estimate x´) can also be found. Because the
calculator converts each formula into a linear regression before
actual calculation takes place, it obtains all statistics — except
coefficients a and b — from converted data rather than from
entered data.
