Hi all,

I'd like to know what is the excel 'slope' formula in JMP. (not 'Bivariate' analysis menu)

If JMP does not have a formula format for 'slope', would you help me to make a JMP formula as below?

Slope

x | y | slop |
---|---|---|

1 | 1 | - |

2 | 2 | ? |

3 | 3 | ? |

4 | 4 | ? |

5 | 5 | ? |

6 | 6 | ? |

Hello,

You can create a column formula for calculating the slope as follows:

- Create a new numeric column entitled Slope.
- Enter the formula for the slope as shown below.
- The Col Sum and Col Mean functions are found under the Statistical functions.

Col Sum( (:X - Col Mean( :X )) * (:Y - Col Mean( :Y )) ) /

Col Sum( (:X - Col Mean( :X )) ^ 2 )

Best,

Stan

Highly recommend to standardize least squares slopes and intercept as a built-in JMP function that can be used directly for formulaes ....

thanks for the post
