01:29 Heteroskedasticity-Robust Standard Error and t-statistic 05:19 Comparison between Robust and Usual Standard Errors and t-statistics 【Five Minute Econometrics】(Econometric Tutorials) Topic 70: What are the Heteroskedasticity-Robust Standard Error and Robust t-statistic? Hi, I am Bob. Welcome back to Five Minute Econometrics. We just learned that if the variance of the error term is not constant, the usual standard errors and t-statistics are not valid. Today, we will explore how to adjust standard errors and t-statistics to make them valid in the presence of heteroskedasticity. It is called the heteroskedasticity-robust standard error or just the robust standard error. It applies to cases when we do not know the form of the variance of the error term. In the presence of heteroskedasticity of unknown form, the robust standard error and the robust t-statistic will be valid in statistical inference. 【Free Courses on My YouTube Channel】 Economics in Real Life:    • Economics in Real Life   Solutions to Introductory Econometrics A Modern Approach 7th Edition:    • Solutions to Introductory Econometrics A M...   Solutions to Microeconomics Theory and Applications with Calculus 5th Edition (Chapters 1 to 10):    • Solutions to Microeconomics Theory and App...   Solutions to Microeconomics Theory and Applications with Calculus 5th Edition (Chapters 11 to 19):    • Solutions to Microeconomics Theory and App...   Introductory Stata:    • Introductory Stata (2022)   Introductory Microeconomics:    • Introductory Microeconomics (2022)   Five Minute Econometrics:    • Five Minute Econometrics (Econometrics Tut...   Five Minute Stata:    • Stata Tutorials   【國語Mandarin】現實生活中的經濟學:    • 【Mandarin國語】現實生活中的經濟學   【粵語Cantonese】現實生活中的經濟學:    • 【Cantonese粵語】現實生活中的經濟學   【粵語Cantonese】微觀經濟學基礎:    • 粵語Cantonese微觀經濟學基礎2022   【國語Mandarin】五分鐘計量經濟學:    • 【Mandarin國語】五分鐘計量經濟學（計量經濟學輔導）   【粵語Cantonese】五分鐘計量經濟學:    • 【Cantonese粵語】五分鐘計量經濟學（計量經濟學輔導）   On the Road:    • On the Road   【Become a Supporter of the channel ($2.99) to get PDF transcripts for】 1.
