Linear fit

kanchanjoshi — Wed, 16 Mar 2016 16:18:51 GMT

Hi,

Somehow I am unable to do a simple task and need help.

How do I create a "Fit each value" and "Linear fit" with Months of a year on x-axis and percent values on y-axis?

I am trying to use "Fit y by x": Looks like the Month-Year column needs some fixing.

I can only select the "Contingency" option; "Bivariate" option becomes deactivated

Thanks for your tolerance.

Your x axis variable is not a continuous variable, it has been created with either an Ordinal or Nominal modeling type. If you change the modeling type for that column to continuous, the bivariate options will be there. I suspect, your X axis column is a Character column, which forces the modeling type to be nominal. You will have to change the column to numeric before changing the modeling type.

Thanks Jim for your prompt help!

JMP would not allow to select modeling type "continuous" though I have changed column formats to "date" and "percentages" in spreadsheet that I used to create data.
