rollis a package that provides fast and efficient computation of rolling and expanding statistics for time-series data. The default algorithm in therollpackage, and suitable for most applications, is anonline algorithm. Based on the speed requirements and sequential nature of many problems in practice...
ANOVA should not be applied to time-series data, as the independence assumption is violated. The issue with independence is that days tend to correlate very highly. For example, if you know that today you have 1400 positive cases, you would expect tomorrow to have a similar number of positiv...

Time-series have an inherent time scale and may be correlated with each other. These relationships can be encoded in a mathematical representation of the process that made the data, i.e., the model. The twin concepts of representation and significance of the data are discussed so that the ...
feasts provides a collection of tools for the analysis of time series data. The package name is an acronym comprising of its key features:Feature Extraction And Statistics for Time Series. The package works with tidy temporal data provided by thetsibblepackage to produce time series features, deco...
As you could see, the data is just constant around1instead of increasing. What am I doing wrong here? (On a side note, I can't pass in string dates like"2001-11-21"into the predict function for some reason. It would be helpful to know why.) ...
STAT 201 Statistical Inference for Data Science 今年新加的课。UBC终于意识到自己的统计课里缺少Coding相关的训练了。“For Data Science”可以解读为“写Code来做...”。所以STAT 201本质上就是“写Code来做STAT 200学的内容"。Coding的语言暂时未知,但是盲猜一波是R。Python也有可能。难度不会高,而且会很实用...
