Iris Dataset Statistical Analysis

Project Description

This project involves reading data from a file named "Iris.csv," performing statistical calculations using various functions, and writing these calculations to a file.

Files

Iris.csv: Contains information such as "Id, SepalLengthCm, SepalWidthCm, PetalLengthCm, PetalWidthCm, Species."
main.c: The main source file of the project. It handles reading data, creating matrices, performing statistical calculations, and writing results to a file.
matrixLib.c: Contains the implementation of functions for matrix operations and statistical calculations.
matrixLib.h: Header file containing function prototypes and necessary definitions.
Makefile: Makefile for compiling and running the project.

Functions

main.c

verileriDiziyeDoldurVeYazdir: Reads the data from the "Iris.csv" file and stores it in an array.
dizidekiVerileriMatriseEkle: Adds data from the array to a 150x4 matrix.
yeniBirDosyayaOzellikYazdir: Performs statistical calculations on the feature matrix and writes them to a file named "IrisStatistic.txt."

matrixLib.c ve matrixLib.h

freeMatrix: Frees the dynamically allocated matrix.
mean: Calculates the mean of a vector.
covariance: Calculates the covariance between two vectors.
correlation: Calculates the correlation between two vectors.
matrixMultiplication: Calculates the product of two matrices.
matrixTranspose: Transposes a matrix.
rowMeans: Calculates the row means of a matrix.
columnMeans: Calculates the column means of a matrix.
covarianceMatrix: Calculates the variance-covariance matrix of a matrix.
determinant: Calculates the determinant of a matrix.

Usage

Place your project files in a folder and then follow the steps below in the terminal or command prompt:

Compile:
```
make program
```
Run:
```
make run
```

Statistics and Results

After running the project, a file named "IrisStatistic.txt" will be created. This file contains the following statistics:

Mean values of SepalLengthCm, SepalWidthCm, PetalLengthCm, and PetalWidthCm features.
Variance values of SepalLengthCm, SepalWidthCm, PetalLengthCm, and PetalWidthCm features.
Correlation between the three pairs of features.
Covariance matrix of the feature matrix.
