Shapiro-Wilk Test of Normality in Stata
Testing continuous variables for their normality of distribution is a common feature of many statistical procedures. In this video, you’ll learn how to use the Shapiro-Wilk test of normality in Stata.

Spearman correlation in R
มุมมอง 148ปีที่แล้ว
Spearman correlation is an alternative to Pearson correlation that can be used when the relationship between variables is monotonic-for example, in the context of two variables, when the variables rise or fall together, but not at a constant rate. In this video, we’ll show you how to use Stata to conduct Spearman correlation and also offer some guidance on when to use Spearman correlation. Spea...
Multicollinearity Testing in Stata
มุมมอง 2.4Kปีที่แล้ว
One of the standard post-regression diagnostic tests is a test for multicollinearity. In this video, we’ll show you to test for multicollinearity after a regression using Stata’s vif command. We’ll show you to run and interpret vif, then adjust your model to eliminate multicollinearity.

Generating z scores in R
มุมมอง 234ปีที่แล้ว
For a normally distributed variable, a z score assigns a number to each data point based on its distance, in standard deviations, from the mean. For example, if the mean of variable iq is 100, with sd 15, then an iq of 100 has a z score of 0, an iq of 85 has a z score of -1, and an iq of 115 has a z score of 1. In this video, we’ll show you how to use R code to create z scores for each value in...
Summary Statistics in R Using Stargazer
มุมมอง 5Kปีที่แล้ว
Often, there are only two considerations for summary statistics in basic statistical analysis: Providing means and standard deviations; and creating good-looking tables. In this video, we’ll show you how to use the Stargazer package in Stata to achieve both of these goals with 5 summary statistics: N, mean, standard deviation, minimum value, and maximum value. Summary Statistics in R Using Star...
Using DataEditR for Easy Editing in R
มุมมอง 283ปีที่แล้ว
In comparison to programs such as Stata and SPSS, R is not necessarily friendly to data editing using a graphic user interface (GUI). Oftentimes, when working in R, you’ll find yourself using code to data edit or perhaps reverting to Excel before importing data back into R. In this video, we’ll show you how to use the DataEditR package in Stata for easier data editing. Using DataEditR for Easy ...
Missing Values in R

Very helpful! Thank you
Thanks it is useful
Great
Error in factor(c("short", "medium", "tall")) : unused argument (c("short", "medium", "tall")) Error is coming like this. Can u explain
thank you for such a clear and concise video!
Fantastic video and great package. Thanks for putting me onto it.
Hello. The vif command doesnt work when I run it. What am I doing wrong?
Thank you so much. This has been very helpfull for me. I just wanted to create twoway line graphs with confidence interval and this has been one step helpful for me.
