How to Install and Use Statistics. mqh Functions
1. Storage: Place library files in the MQL/Libraries directory to ensure they are accessible to your projects.
2. Implementation: Include the library in your code using the #import directive, ensuring you match the exact function names and parameters.
3. Compilation: Ensure the library is present in the directory before you compile your main EA or script, as the compiler links them during this phase.
4. Management: Keep libraries organized in sub-folders if you manage many custom functions to maintain a clean project structure.
Frequently Asked Questions
Q: What is a library file used for? A: Libraries store reusable code modules, allowing you to centralize common logic used by multiple EAs or indicators.
Q: Is a library executable? A: No, libraries are non-executable files containing functions; they must be imported into an EA, indicator, or script to function.
Q: Can I update a library while the platform is running? A: You should compile your EA or script after updating a library to ensure the latest code changes are integrated.

This library was first published in CodeBase at MQL4 - . Some typos have been detected and corrected while transferring the functions to MQL5. The code has become more intuitively clear. Most functions have been written using the algorithms from S. Bulashov's book "Statistics for traders".The library functions are as follows:
The file can be included in the projects requiring random sample parameters processing, its parameters evaluation, histograms etc.
Let's examine the call of some functions:
As you can see, most functions require the values (as input parameters) that can be calculated using other functions.
For example:
To calculate the variance, we have to calculate the mean at first. That gives a certain advantage regarding the calculations optimization. In case it is necessary to calculate the variance for several times, it will be better to find the mean once instead of doing it several times inside the function. That will save time.
This feature applies to most functions of the library.
