I will need the LaTEX software and a step by step use of it. I need someone who will thoroughly guide me in the use of LaTex in statistical analysis and arrangement of data.
Hello, as I know and use LaTeX, it is a typesetting software (for typesetting documents), not a software used for statistical analysis (there are some latex-packages like sweave, which implement R-commands and outputs directly into LaTeX-articles). So, check https://www.latex-project.org/
...there are lot of them, it depends on what do you need.
R-software is free, there are lot of packages for a wide field of statistical methods, RStudio (or Rcommander, Rattle, and others) provides a graphical interface for R, if you are not familiar with typing source code (see https://www.r-project.org/ ).
There are also some plugins for MS Excel for basic statistics, see www.real-statistics.com. Then SAS, IBM SPSS, and many others.
