Add functions to bin data

[christianp]

Data binning is the process of grouping data into a fixed number of smaller bins.

There should be functions to do this with lists of numbers in JME. There are a few ways to do it, depending on how much information you can give in advance, and how much you infer from the data.

So we need to define a few versions of bin that take different arguments. I'm not sure exactly what their names should be.

Here are some example inputs and outputs:

For the function bin(values, bin_width):

values: [1,2,3,4] bin_width: 2 Returns: [ [1,2], [3,4] ]

values: [10,11,12,13] bin_width: 2 Returns: [ [10,11], [12,13] ]

values: [13,12,11,10] bin_width: 2 Returns: [ [10,11], [12,13] ]

values: [1, 8] bin_width: 3 Returns: [ [1], [], [8] ]

values: [0,2,2,3,6,10,11,13] bin_width: 3 Returns: [ [0,2,2], [3], [6], [10,11], [13] ]

values: [1.36, 1.45, 1.60, 1.23, 1.25, 1.66, 1.10] bin_width: 0.1 Returns: [ [1.1], [1.23, 1.25], [1.36], [1.45], [], [1.60, 1.66] ]

For the function bin(values, num_bins): bin_width = (max(values) - min(values))/num_bins

values: [1,2,3,4] num_bins: 2 Returns: [ [1,2], [3,4] ]

values: [10,11,12,13] num_bins: 2 Returns: [ [10,11], [12,13] ]

values: [10,11,12,13] num_bins: 3 Returns: [ [10], [11], [12,13] ]

values: [13,12,11,10] num_bins: 3 Returns: [ [10], [11], [12,13] ]

values: [1, 8] num_bins: 2 Returns: [ [1], [8] ]

values: [0,2,2,3,6,10,11,13] num_bins: 5 Returns: [ [0,2,2], [3], [6], [10], [11,13] ]

values: [1.36, 1.45, 1.60, 1.23, 1.25, 1.66, 1.10] num_bins: 4 Returns: [ [1.10, 1.23], [1.25, 1.36], [1.45], [1.60, 1.66] ]

---

For the function bin(values, start, end, num_bins): bin_width = (end - start)/num_bins

values: [1,2,3,4] start: 0 end: 5 num_bins: 2 Returns: [ [1,2], [3,4] ]

values: [10,11,12,13] start: 10 end: 15 num_bins: 2 Returns: [ [10,11], [12,13] ]

values: [10,11,12,13] start: 0 end: 15 num_bins: 3 Returns: [ [], [], [10, 11, 12,13] ]

values: [0,2,2,3,6,10,11,13] start: 0 end: 15 num_bins: 5 Returns: [ [0,2,2], [3], [6], [10,11], [13] ]

values: [1.36, 1.45, 1.60, 1.23, 1.25, 1.66, 1.10] start: 1 end: 2 num_bins: 10 Returns: [ [], [1.10], [1.23,1.25], [1.36], [1.45], [], [1.60, 1.66], [], [], [] ]

@JanOnBread here's an issue describing how I want the bin functions to work.

[yashmonk123]

can I take this issue?

[yashmonk123]

And also can you please specify where we need to add that function and in which language you want

@yashmonk123 thanks for offering to help, but @janonbread took this on. I forgot to assign this issue to her - sorry for the inconvenience!
