Rare events prediction in complex technical systems has been very interesting and critical issue for many industrial and commercial fields due to huge increase of sensors and rapid growth

Though Hotelling’s T-square method is applicable for many multi-dimensional data sets, this method has a fundamental assumption that the data follow a unimodal distribution. So, when the

Among many statistical anomaly detection techniques, Hotelling’s T-square method, a multivariate statistical analysis technique, has been one of the most typical method. This method

This example was authored by the MathWorks community.

The previous methods, Hotelling’s T-square method and Gaussian mixture model, use Gaussian distribution-based parametric model. However, in practical situation, sometimes data

Demonstration of dot product, orthogonality also includes some vector addition. Information from this tutorial is used in qr decomposition and multiple regression regression approach

The time series from a SDOF is computed using the central difference method, and a white noise is used as an input force.

This demo showcases visualization and analysis (heavy statistics) for forecasting energy usage based on historical data. We have access to hour-by-hour utility usage for the month of

Statins are the most common class of drugs used for treating hyperlipdemia. However, studies have shown that even at their maximum dosage of 80 mg, many patients do not reach LDL cholesterol

This tutorial describes multivariate guassians as it walks through the major functioniality of the mmvn toolkit

Consider the hypercube and an inscribed hypersphere with radius . Then the fraction of the volume of the cube contained in the hypersphere is given by:

The dynamic response of a 100 m high clamped-free steel beam is studied. Simulated time series are used, where the first three eigenmodes have been taken into account. More precisely, the

Linear Mixed-Effect (LME) Models are generalizations of linear regression models for data that is collected and summarized in groups. Linear Mixed- Effects models offer a flexible

In this demo, we will perform statistical analysis on automotive fuel economy data provided by the United States Environmental Protection Agency. We will see how the Statistics Toolbox™

This tutorial will go over some of the functions available for making inferences and testing hypothesis. I assume that you know how to construct a model using encode. If not see the

Linstats package provides a uniform mechanism for building any supported linear model. Once built the same model can be analyzed in many ways including least-squares regression, fit and

故障が発生した場合の損失が甚大である場合、保守的なスケジュールで（より短い期間で）メンテナンスを行うことで、故障の発生を避けるアプローチはよく取られます。 ただこのアプローチでは結果として必要以上にメンテナンスを実施することに繋がることが多く、余計なコストとなります。

This is a walkthrough of the Demo shown in the 30 November 2006 Webinar titled "Using Statistics for Uncertainty Analysis in System Models". The demo covers two basic topics:

Hypothesis testing based on a model that is invalid can lead to faulty conclusions. this tutorial goes over a few basic diagnostic procedures that can be used to test whether a model is valid.

多変数の時系列データを複数使用します。それぞれの時系列データはそれぞれ同じ型ですが、別々のエンジンで計測しされたものです。 通常エンジンにはユーザーにはわからない様々なレベルの摩耗、製造変動が初期段階から存在しますが、故障しているわけではありません。

The state of Connecticut collects data on repairs performed to their fleet of vehicles. The data can be accessed here: https://catalog.data.gov/dataset/vehicle-repairs

In order to illustrate some of the numerical calculations required for testing hypothesis on canonical variance components based on the LRT statistic (37), as presented in Example 3, let us

To support the port passing problem I'll need to derive some recurrence equations that allow us to talk about the expected number of steps given that we win Gambler's Ruin (rather than lose).
