variance stats

First, the basic principles of statistics12 Sample t Test Condition: ① Both obey normal distribution, ② two population variance is equal, namely variance homogeneity.2 pairs of T-Test conditions: The difference of the overall normal distribution can

This article mainly introduces some suggestions for reuse and reduction in Python programming, from the IBM official technical documentation. For more information, see Back to nature Many popular toys are based on the concept of simple building

Innocence Many popular toys are based on such a concept: simple building blocks. These simple blocks can be combined in a variety of ways to construct a new piece of work-sometimes even completely unexpected. This concept also applies to real-life

No matter what field of research or statistical investigation you are in, the significance test is widely used as a method to determine whether there is a difference between two or more datasets. The author, as a researcher in the field of

Basic R packages have implemented many of the functions of traditional multivariate statistics, however many of the other packages provided by Crna provide a more in-depth multivariate statistical approach, the following package is mainly divided

PCA (Principal Component analysis) is also known as the Karhunin-low transformation (Karhunen-loeve Transform), a technique used to explore high-dimensional data structures. PCA is often used for exploration and visualization of high-dimensional
