CORRELATIONS Subcommand (GENOSTAT command)

The CORRELATIONS subcommand is used to compute correlation coefficients to explore relationships among GENOSTAT variables.

VARIABLES

Specify the variables for analysis. This is a mandatory keyword. You must specify at least 2 variables.

Example:

/CORRELATIONS  VARIABLES=overrepresented_seq_count median_phred_last_10bp

PEARSON

Use this keyword to compute Pearson correlations. The default value is PEARSON=FALSE

Example:

/CORRELATIONS  VARIABLES=overrepresented_seq_count median_phred_last_10bp  PEARSON=TRUE

SPEARMAN

Use this optional keyword to compute Spearman correlations.

Example:

/CORRELATIONS  VARIABLES=overrepresented_seq_count median_phred_last_10bp  PEARSON=FALSE  
    SPEARMAN

KENDALL

Use this optional keyword to compute Kendall’s tau.

Example:

/CORRELATIONS  VARIABLES=overrepresented_seq_count median_phred_last_10bp  PEARSON=FALSE  KENDALL

TWOTAIL

Use this optional keyword to perform two-tailed significance tests.

Example:

 /CORRELATIONS  VARIABLES=overrepresented_seq_count median_phred_last_10bp  PEARSON=FALSE  KENDALL 
    TWOTAIL

ONETAIL

Use this optional keyword to perform one-tailed tests.

Example:

/CORRELATIONS  VARIABLES=overrepresented_seq_count median_phred_last_10bp  PEARSON=FALSE  KENDALL 
    ONETAIL

The keywords TWOTAIL and ONETAIL are mutually exclusive.
