Basic Features of STATPerl

Data Import and Handling

STATPerl supports various data formats, including CSV, TSV, and text files. Here’s a simple example of how to read a CSV file:

use STATPerl; my $data = STATPerl::Import->new(file => 'data.csv'); $data->load(); 

Analyzing Data

STATPerl offers a range of statistical functions that make it easy to analyze your dataset. Here are a few commonly used methods:

1. Descriptive Statistics

You can get a summary of your data using:

   my $summary = $data->summary();    print $summary; 

1. Hypothesis Testing

To perform a t-test:

   my $t_test_results = $data->t_test(variable1 => 'column1', variable2 => 'column2');    print $t_test_results; 

1. Regression Analysis

For linear regression, you might use:

   my $regression = $data->linear_regression(dependent => 'output_column', independent => ['input1', 'input2']);    print $regression;

Visualizing Data

Data is easier to understand when presented visually. STATPerl supports multiple visualization options. Here’s how to create a basic plot:

use STATPerl::Graph; my $graph = STATPerl::Graph->new(data => $data); $graph->scatter_plot(x => 'column1', y => 'column2'); 

This code snippet creates a scatter plot that helps in visualizing the relationship between two variables in your dataset.
