Its stationarity is also briefly discussed. #Statistics #Time Series #Autocorrelation #R Time series Aug 28, 2020 | 11 min read Introduction We introduce some basic ideas of time series analysis and stochastic processes. Of particular importance are the concepts of stationarity and the autocovariance and sample autocovariance functions. #Statistics #Time Series #Autocorrelation #Visualization #Regression #Independent Samples Linear algebra Aug 26, 2020 | 8 min read Matrices Matrix algebra plays an important role in many areas of statistics, such as linear statistical models and multivariate analysis. In this chapter we introduce basic terminology and some basic matrix operations. We also introduce some basic types of matrices. #Linear Algebra #Matrix #Operations Mathematical statistics Apr 21, 2020 | 9 min read Linear Models So far we’ve finished the main materials of this course - estimation and hypothesis testing.
