![Survival Analysis [Simply Explained]
This video is all about survival time analysis. We start with the question what a survival time analysis is, then we come to the important point what the censoring of data means and finally we discuss the Kaplan Meier Curve, the log rank test and the Cox regression.
Survival time analysis is a group of statistical methods in which the variable under study is the time until an event occurs.

![Spearman Rank Correlation [Simply explained]
Spearman rank correlation examines the relationship between two variables. The Spearman rank correlation is the non-parametric counterpart of the Pearson correlation. There is an important difference between the two correlation coefficients! The Spearman correlation does not use the initial data, but the ranks of the data.
