Info

What is GAUSS?

An Introduction to GAUSS

The GAUSS Platform is an interactive environment designed for math and statistics, which has been used by leaders in data-dependent fields at major institutions for more than 30 years.

Comprehensive Environment for Modeling and Analysis

The GAUSS base platform is a complete analysis environment with the built-in tools you need for estimation, forecasting, simulation, visualization and more.

It allows you to stay ahead of the curve by giving you the tools you need to modify our algorithms or create the latest and greatest from the ground up.

The GAUSS Platform provides a fully interactive environment for exploring data, performing calculations and analyzing results. These interactive features speed up your workflow, while the exceptionally fast analytics engine will speed up your computations.

GAUSS - Time series

The GAUSS analytics engine has been designed to be extremely lightweight and efficient while making the most use of your hardware. From a small laptop to a large cluster, nothing scales as well as GAUSS.

Intuitive and powerful interactive and programmatic methods make it easy to create beautiful and professional 2D and 3D graphics to analyze your data and present your findings. Your high-resolution GAUSS graphics can be exported to many popular formats such as PNG, PDF, SVG, TIFF and more.

New features in GAUSS 23

GAUSS 23 is the latest and most user-friendly version of GAUSS, designed to streamline your research process by making it easier to find, import, and model data.

Data at Your Fingertips

GAUSS 23 - Data at your fingertip
  • Access millions of global economic and financial data series with FRED and DBnomics integration.
  • Aggregate, filter, sort, and transform FRED data series during import.
  • Search FRED series from GAUSS.

Load Data from Anywhere on the Internet

// Load an Excel file from the aptech website
file_url = “http://www.aptech.com/wp-content/uploads/2019/03/skincancer2.xlsx”;
skin_cancer = loadd(file_url);

// Print the first 5 rows of the dataframe
head(skin_cancer);

GAUSS 23 - Table data from the internet

Simplified Data Loading with…

Automatic Type Detection

Previous versions required formula strings with keywords to specify date, string, and categorical variables from some file types.

GAUSS 23 - Load variables 1

Smart data type detection in GAUSS 23 figures out the variable type so you do not have to specify it manually. Automatically detects nearly 40 popular date formats.

GAUSS 23 - Load variables 2

Automatic Header and Delimiter Detection

Replace old code like this:

load X[127,4] = mydata.txt;


with

X = loadd(“mydata.txt”);

Automatically handles:

  • Present or absent header row.
  • Delimiter (tab, comma, semi-colon or space).
  • Number of rows and columns.
  • Variable types.

First-Class Dataframe Storage

GAUSS 23 - Dataframe storage

No new code to learn, use the .gdat file extension with loadd and saved to load and store your dataframes.

Expanded Quantile Regressions

GAUSS 23 - Quantile regressions

hitters = loadd(“islr_hitters.xlsx”);
tau = 0.90;
call quantileFit(hitters, “ln(salary) ~ AtBat + Hits + HmRun”, tau);

GAUSS 23 - Quantile regressions table
  • New kernel estimated variance-covariance matrix.
  • Up to 4x speed improvement.
  • Expanded model diagnostics including pseudo R-squared, coefficient t-statistics and p-values, and degrees of freedom.

Kernel Density Estimations

GAUSS 23 - Kernel denisty
  • Estimate unknown probability functions with 13 available kernels.
  • Automatic or user-specified bandwidth.
  • Kernel density plots with easy-to-use options for customization.

Improved Covariance Computations

// Load data
fname = getGAUSShome(“examples/auto2.dta”);
auto = loadd(fname);

// Declare control structure
struct olsmtControl ctl;
ctl = olsmtControlCreate();

// Turn on residuals
ctl.res = 1;

// Turn on HAC errors
ctl.cov = “hac”;
call olsmt(auto, “mpg ~ weight + foreign”, ctl);

GAUSS 23 - Improved covariance table
  • New procedure for computing Newey-West HAC robust standard errors.
  • All robust covariance procedures now include the option to turn off small sample corrections.
  • Expanded dataframe and formula string compatibility.

New Functions for Data Cleaning and Exploration

between

Returns a binary vector indicating which observations fall in a specified range. It can be used with selif to select rows. Dates and ordinal categorical columns are supported.

// Return a 1 if the observation is between the listed dates
match = between(unemp[.,”DATE”], “2020-03”, “2020-08”);

// Select the matching observations
unemp = selif(unemp, match);

GAUSS 23 - between function

where

Provides a convenient and intuitive way to combine or modify data. It returns elements from either a or b depending upon condition.

// Daily hotel room price
hotel_price = { 238, 405, 405, 329, 238 };

// Daily temperature forecast
temperature = { 89, 94, 110, 103, 97 };

// Decrease the price by 10% if the
// temperature will be more than 100 degrees
new_price = where(temperature .> 100,
hotel_price .* 0.9,
hotel_price);

new_price = 238 405 364.50 296.10 238

  • Explore sample symmetry and tails with skewness and kurtosis functions.
  • Test for normality using the new JarqueBera function.

Speed-ups and Efficiency Improvements

  • Up to 10x speed-up and 50% decrease in memory usage for lag creation with shiftc and lagn.
  • Up to 2x speed-up (or more for large data) and 50% decrease in memory usage for miss, missrv.
  • Up to 2x speed-up (or more for large data) and 50% decrease in memory usage for element-by-element mathematical (+, -, .*, ./), relational (.>, .<, .>=, .<=, .==, .!=) and logical (.and, .not, .or, .xor) operators.
  • Up to 100x speed-up for some cases with indsav.
  • Up to 40% speed-up for reclassify.
  • Up to 3x speed-up for loading Excel® files with loadd and the Data Import Window.
