Title Excel-based Analysis Methods for Iddaa: Predictive Models, Data Processing, and Practical Tools Abstract This paper evaluates Excel-based analysis techniques for iddaa (Turkish sports betting) data. It compares descriptive statistics, simple predictive models (logistic regression approximations, moving averages, Elo-like ratings) implementable in Excel, and basic automation with VBA. Using historical match and odds data, we measure predictive accuracy, calibration, and profitability under realistic bankroll rules. Results show that well-prepared features and simple rating systems improve predictions versus raw odds, while Excel+VBA is sufficient for lightweight backtesting and reporting but has scalability limits. Keywords iddaa, sports betting, Excel, VBA, predictive modelling, backtesting, Elo, logistic approximation 1. Introduction

Context: iddaa market, data sources, betting odds as information. Motivation: accessibility of Excel for analysts; need for reproducible lightweight tools. Contributions: implementations of feature engineering, rating systems, simple models in Excel; empirical evaluation.

2. Literature Review

Sports betting prediction literature: odds efficiency, Elo ratings, Poisson models. Use of spreadsheets in analytics and limitations. (Include citations to key works — add via web search when finalizing.) iddaa excel analiz programlar hot

3. Data

Data sources: historical iddaa match results, odds, timestamps, leagues, home/away. Preprocessing steps: cleaning, handling canceled matches, syncing odds and match times. Suggested sample dataset schema (columns): Date, League, HomeTeam, AwayTeam, HomeGoals, AwayGoals, HomeOdds, DrawOdds, AwayOdds.

4. Feature Engineering in Excel

Basic features: goal differences, form (last N results), head-to-head aggregates. Rating systems: Excel implementation of Elo-like ratings using iterative updates. Odds-derived features: implied probabilities (1/odds normalized), overround adjustment. Example formulas:

ImpliedProb = 1 / Odds NormalizedProb = ImpliedProb / (HomeImplied+DrawImplied+AwayImplied)

5. Models Implementable in Excel

Baseline: favorite-win rate, implied probability calibration. Elo rating prediction: expected score via logistic function. Logistic regression approximation: using Excel’s Solver to fit coefficients on features (or use LINEST for linear probability). Moving-average and Poisson-intended approximations. VBA snippets to automate iterative rating updates and batch predictions.
