KITCHENER, Ontario, Sept. 15, 2020 (GLOBE NEWSWIRE) -- SigmaXL Inc., a leading provider of user-friendly Excel Add-ins for Statistical and Graphical analysis, announces the release of SigmaXL Version 9.
“SigmaXL was designed from the ground up to be a cost-effective, powerful, but easy to use tool that enables users to measure, analyze, improve and control their service, transactional, and manufacturing processes. As an add-in to the already familiar Microsoft Excel, SigmaXL is ideal for Lean Six Sigma training or use in a college statistics course. Version 9 adds Time Series Forecasting and advanced control charts,” said John Noguera, CTO, SigmaXL.
New features in Version 9 include:
Powerful and Easy-to-Use Time Series Forecasting and Control Charts for Autocorrelated Data
Run Chart
Autocorrelation Function (ACF)/Partial Autocorrelation (PACF) Plots
Cross Correlation (CCF) Plots with Pre-Whiten Data option
Seasonal Trend Decomposition Plots
Spectral Density Plot with Detection of Seasonal Frequency
Exponential Smoothing Forecast. Models include:
Additive/Multiplicative Error
Additive/Additive Damped Trend
Additive/Multiplicative Seasonal
Multiple Seasonal Decomposition
Exponential Smoothing Residuals Control Chart for autocorrelated data
Autoregressive Integrated Moving Average (ARIMA) Forecast with support for:
Predictors (Continuous and/or Categorical)
Multiple Seasonal Decomposition
ARIMA Residuals Control Chart for autocorrelated data
Utilities: Difference Data, Lag Data, Interpolate Missing Values
Model Features:
ARIMA and Exponential Smoothing models are fully automatic or user spcified
Utilizes modern State Space and Kalman Filter models for accurate parameter estimation
ARIMA estimates missing values with Kalman Filter; Exponential Smoothing uses seasonally adjusted linear interpolation
Out-of-Sample (Withhold) one-step-ahead and multi-step-ahead forecast errors
SigmaXL’s forecasting capabilities were evaluated using the benchmark standard M4 forecast competition data, a total of 100,000 data sets with Yearly, Quarterly, Monthly, Weekly, Daily and Hourly data. Using a hybrid average of automatic Exponential Smoothing and ARIMA, the Overall Weighted Average forecast accuracy score outperformed three well-known commercial forecast software packages.
