This are the formulas that are used to calculate the Response surface methodology.

The formula is put in to matrices.

To Calculate the factors the following formula is used

To calculate the correlation coefficient the following formulas are used.

df | SS | MS | |

Total | n-1 | ||

Regression | k | ||

Error | n-k-1 |

= inverse matrix

= y value predicted by the formula

= Average y value

= error

= multiple correlation coefficient
