将Python季节性成分初始化代码转F#后行数剧增，求优化方案

I'm in the process of converting a Python function for initializing seasonal components into F#, but I've noticed the F# version has significantly more lines of code. I'm unsure if my approach has issues or if there's room for optimization.

Below are the relevant array definitions, code snippets, and full code for both languages—could someone help me review this and suggest improvements?

Input Array #

• Python: series = [30,21,...,26,32]
• F#: let series = [|30;21;...;26;32|]

Function Definition (Part 1) #

Original Python Code #

def initial_seasonal_components(series, slen):
    ...

My Converted F# Code #

open System.Collections.Generic
let initial_seasonal_components (series : int []) (slen : int) : Dictionary<int, double> =
    ...

Loop Implementation (Part 2) #

Original Python Code #

for i in range(slen):
    ...

My Converted F# Code #

for i in 0 .. slen-1 do
    ...

Full Code #

Complete Python Code #

series = [30,21,...]
def initial_seasonal_components(series, slen):
    ...

Complete F# Code #

open System.Collections.Generic
let series = [|30;21;...|]
let initialAeasonalComponents (series : int []) slen : Dictionary<int, double> =
    ...
initialAeasonalComponents series 12

My Questions #

• Are there any errors in my F# implementation?
• Is this already the most optimized version of the code, or can it be streamlined further?
