周末花了一天时间,写了篇英文博客 "What Is a Time-Series Database and Why Do I Need One?",分享给大家,如下: (同事已经翻译了中文,方便大家阅读:什么是时序数据库?我们为什么需要时序数据库?|时序数据库 - TDengine - 涛思数据) A time-series database (TSDB) is a database management system that ...
1) A plot of data from a time series, which shows a cyclical pattern – please show a time series plot and identify the length of the major cycle. 2) Data from a full factorial or fractional factorial experiment with at least 2 factors – please identify the factors and the dependent ...

The magnetization curves are just one example of how we could picture the system evolving over time. We might also consider recording 2D time series, as the snapshot of the overall state at each point in time. Or there might be other interesting aggregate variables to measure at each step,...
It has been recognized that the two-phase version of the interrupted time-series design can be frequently modeled using a four-parameter design matrix. There are differences across writers, however, in the details of the recommended design matrices to be used in the estimation of the four parame...
Schema Design and Evolution How do you store time series data in a database? In relational databases the answer is somewhat straightforward; you store each event as a row within a table. Let’s say you were monitoring the amount of system memory used per second. In that example you would...
You can start a time series analysis by building a design matrix (XtXt), also called a feature or regressor matrix, which can include current and past observations of predictors ordered by time (t). Then, apply ordinary least squares (OLS) to the multiple linear regression (MLR) model ...
(SPM) to analyze time-series contributions of body segments (arms, legs, trunk) to three-dimensionalHon uphill, downhill, and level grades. The trunk and prosthetic-side leg contributions toHat toe-off when using the active prosthesis were more similar to non-amputees compared to using a ...
