Performance Analytics – Formula indicator doesn’t support round() or max()

Hi,

I’m kinda new to Performance Analytics and I'm working on a formula indicator. I’m trying to apply a normalization formula like this:

round(max(-0.000000053 * score^3 + 0.0000411 * score^2 - 0.0109 * score + 1, 0) * 100)

Where score is another indicator.

However, in PA formula indicators:

round() is not recognized

max() is not recognized

So the formula fails with errors like “function not defined”.

Is there a way to use functions like round or max in PA formula indicators?

If not, how do you usually handle this kind of logic? 

Thanks

Go with a Scripted Indicator — it's the most direct solution since your logic lives entirely within PA.

Navigate to Performance Analytics → Indicators, create a new indicator, set the type to Script, and use:

(function() {
    var score = /* your source score value */;

    var raw = -0.000000053 * Math.pow(score, 3)
            +  0.0000411   * Math.pow(score, 2)
            -  0.0109      * score
            +  1;

    return Math.round(Math.max(raw, 0) * 100);
})();

This gives you full Math.* support, runs during normal PA collection jobs, and works with breakdowns and dashboards just like any other indicator — no extra tables, fields, or business rules needed.
