Formula applicationIF(MONTH(A151)=MONTH(A150),NA(),COUNTIF(W151:W181,1)*100/(COUNTIF(W151:W181,1)+COUNTIF(W151:W181,0))) . This is a formula applied in excel to create a new column, where Column A has date & column W contains only 0 & 1 as values. How to apply this same formula in JMP if we have columns A & W values.
Advanced Statistical ModelingRe: Formula applicationYour request is a bit unclear, but I think I am close to what you want - see attached file. I created a column of random dates and then sorted them. The W column is a random vector of 0 and 1 values. The formula counts the fraction of 1 values in the next 30 days after a change in months. If this isn't what you want, can you either explain it more clearly or post a simple example. Remember, JMP is not a spreadsheet, so Excel formulas like CountIF don't always translate well.
