Comparison of Two Sample Dependent (Paired t-test)
The comparison of two paired samples becomes interesting to discuss this time. This two-sample comparison test is often analyzed using a paired t-test. Many researchers or students who are conducting research choose to use this test.
How to Compute Spearman Rank Correlation Test
A correlation test is still often an option to solve problems in research. The correlation test includes the Pearson correlation test, Spearman rank correlation test, and chi-square test. Determining the type of correlation test to use depends on the measurement data scale. Well, on this occasion, I will discuss using the Spearman rank correlation test.
Autocorrelation Test on Time Series Data using Linear Regression
The autocorrelation test is one of the assumptions of linear regression with the OLS method. On this occasion, I will discuss the autocorrelation test on time series data. Before discussing the autocorrelation test, you need to know first that the autocorrelation test was conducted on time series, not cross-sectional data.
Regression Assumption Test: How and Why to Do?
Incidentally, the topic that I will discuss this time is the linear regression assumption test using the ordinary least square method. “Why do we have to use the linear regression assumption test? Can I directly do a regression analysis?” To answer this question, you need to go back a little bit by turning page after page from a book on econometric theory or socio-economic statistics, okay? One of the main points that you need to pay attention to is that you are doing an estimate when you analyze research data and then choose regression as an analysis tool.
