Comprehensive Time Series Forecasting

Trend & Seasonality Analysis

Decompose time series data to identify underlying trends, seasonal patterns, and cyclical components. Understand the structure of your data to choose the most appropriate forecasting method.

Moving Averages & Exponential Smoothing

Apply simple and weighted moving averages, exponential smoothing, and Holt-Winters methods for different data patterns. Automatically optimize smoothing parameters for best fit.

ARIMA Modeling

Implement AutoRegressive Integrated Moving Average (ARIMA) models for sophisticated time series forecasting. Includes model selection, parameter estimation, and diagnostic checking.

Seasonal Forecasting

Handle seasonal data with specialized seasonal decomposition and forecasting methods. Account for multiple seasonal patterns and irregular seasonal effects.

Advanced Predictive Analytics & Modeling

Regression-Based Forecasting

Use linear and polynomial regression models to forecast based on explanatory variables. Incorporate external factors and leading indicators into your forecasting models.

Ensemble Methods

Combine multiple forecasting methods to improve accuracy through ensemble techniques. Weight different models based on their historical performance and reliability.

Forecast Accuracy Metrics

Evaluate forecast performance using MAE, MAPE, RMSE, and other accuracy metrics. Compare different forecasting methods and select the best performing model.

Confidence Intervals & Uncertainty

Generate prediction intervals and confidence bands around forecasts. Quantify forecast uncertainty and provide probabilistic predictions for risk management.

Frequently Asked Questions

How much historical data do I need for forecasting?

The template provides guidance on minimum data requirements for different forecasting methods. Generally, you need at least 2-3 seasonal cycles for seasonal data, or 20-30 observations for non-seasonal data.

Which forecasting method should I use?

The template includes a decision framework to help you choose the best method based on your data characteristics, forecast horizon, and accuracy requirements. It compares different methods automatically.

Can it handle missing data points?

Yes, the template includes interpolation methods to handle missing values and gaps in time series data. It provides options for linear, polynomial, and seasonal interpolation.

How do I validate forecast accuracy?

The template includes cross-validation techniques and out-of-sample testing to validate forecast performance. It provides multiple accuracy metrics and backtesting procedures.

Can it forecast multiple related variables?

The template supports multivariate forecasting using Vector Autoregression (VAR) models to forecast multiple related time series simultaneously while accounting for their relationships.

How do I analyze data?
To analyze spreadsheet data, just upload a file and start asking questions. Sourcetable's AI can answer questions and do work for you. You can also take manual control, leveraging all the formulas and features you expect from Excel, Google Sheets or Python.
What data sources are supported?
We currently support a variety of data file formats including spreadsheets (.xls, .xlsx, .csv), tabular data (.tsv), JSON, and database data (MySQL, PostgreSQL, MongoDB). We also support application data, and most plain text data.
What data science tools are available?
Sourcetable's AI analyzes and cleans data without you having to write code. Use Python, SQL, NumPy, Pandas, SciPy, Scikit-learn, StatsModels, Matplotlib, Plotly, and Seaborn.
Can I analyze spreadsheets with multiple tabs?
Yes! Sourcetable's AI makes intelligent decisions on what spreadsheet data is being referred to in the chat. This is helpful for tasks like cross-tab VLOOKUPs. If you prefer more control, you can also refer to specific tabs by name.
Can I generate data visualizations?
Yes! It's very easy to generate clean-looking data visualizations using Sourcetable. Simply prompt the AI to create a chart or graph. All visualizations are downloadable and can be exported as interactive embeds.
What is the maximum file size?
Sourcetable supports files up to 10GB in size. Larger file limits are available upon request. For best AI performance on large datasets, make use of pivots and summaries.
Is this free?
Yes! Sourcetable's spreadsheet is free to use, just like Google Sheets. AI features have a daily usage limit. Users can upgrade to the pro plan for more credits.
Is there a discount for students, professors, or teachers?
Currently, Sourcetable is free for students and faculty, courtesy of free credits from OpenAI and Anthropic. Once those are exhausted, we will skip to a 50% discount plan.
Is Sourcetable programmable?
Yes. Regular spreadsheet users have full A1 formula-style referencing at their disposal. Advanced users can make use of Sourcetable's SQL editor and GUI, or ask our AI to write code for you.
