Mendix is a low-code development platform that allows users to create custom business applications, but it doesn't have built-in functions for calculating standard deviation. However, you can use JavaScript in Mendix to calculate standard deviation. Here's how:
Here's a sample JavaScript code to calculate the standard deviation in Mendix:
// Define the input parameter(s)
const inputData = input.data1;
// Calculate the mean
const mean = inputData.reduce((acc, val) => acc + val, 0) / inputData.length;
// Calculate the variance
const variance = inputData.reduce((acc, val) => acc + Math.pow(val - mean, 2), 0) / inputData.length;
// Calculate the standard deviation
const standardDeviation = Math.sqrt(variance);
// Return the standard deviation as the output of the action
output = { result: standardDeviation };
In this code, input.data1
represents an array of numbers passed in as input to the JavaScript action. The output is returned as an object with the result
property containing the calculated standard deviation.
