NAME

Statistics::Discrete - Perl extension for blah blah blah

SYNOPSIS

 use Statistics::Discrete;

 # construct a new class
 my $sd = Statistics::Discrete->new();
 
 # add data using an array
 $sd->add_data((2,5,7,2,1,7,3,3,7,333));
 
 # ---- Descriptive Statistics ---- #

 # Count the number of samples
 my $count = $sd->count(); 
 # Minimum data value
 my $min = $sd->minimum(); 
 # Maximum data value
 my $max = $sd->maximum(); 
 # Mean 
 my $mean = $sd->mean(); 
 # Variance
 my $variance = $sd->variance(); 
 # Standard Deviation
 my $standard_deviation = $sd->standard_deviation(); 


 # ---- Distributions ---- #

 my $fd = $sd->frequency_distribution();
 my $pmf = $sd->probability_mass_function();
 my $cdf = $sd->empirical_distribution_function();
 my $ccdf = $sd->complementary_cumulative_distribution_function();


 # ---- Binning ---- #
 # binning influences the way the distributions
 # are returned
 my $binning_type = NO_BINNING;   # DEFAULT
 $binning_type = LIN_BINNING; 
 $binning_type = LOG_BINNING; 
 $sd->set_binning_type($binning_type);

 $sd->set_optimal_binning();
 my $num_of_bins = 3;
 $sd->set_custom_num_bins($num_of_bins);
 
 # return the bins currently used
 my $cur_bins = $sd->bins();

 # compute linear bins starting from the data
 my $lin_bins = $sd->compute_lin_bins($num_of_bins);
 my $log_bins = $sd->compute_log_bins($num_of_bins);

 # ---- Data Input ---- #

 # add data from file
 $sd->add_data_from_file("./data.txt");
