To compute the Rate of Change (ROC) in Scala, you can use the following code snippet:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
def computeROC(data: List[Double]): List[Double] = {
  data.zip(data.drop(1)).map { case (current, next) =>
    (next - current) / current
  }
}

val data = List(10.0, 15.0, 20.0, 25.0, 30.0)
val rocValues = computeROC(data)

println(s"Rate of change values: $rocValues")


In this code snippet, the computeROC function takes a list of Double values as input and computes the Rate of Change (ROC) between each consecutive pair of values. It uses the zip function to pair each element with the next element in the list, and then calculates the ROC by subtracting the current value from the next value and dividing by the current value. The result is a list of ROC values for each pair of consecutive values in the input list.


You can then call the computeROC function with your input data and print the resulting ROC values.
