gx.summary: Compiles a Table of Summary Statistics

Description

This function is a sub-engine between the main summary statistics engine, gx.stats, and the gx.summary.* display functions. Its sub-engine function is to select the required results from the gx.stats computations, and additionally compute 95% confidence bounds on means.

Usage

gx.summary(xx, log = log, iftell = iftell)

Arguments

xx

name of the variable to be processed.

log

if it will be required to display summary statistics following a log10 transformation of the data, set log = TRUE.

iftell

passes the value of iftell for controlling the display of the NA count to function remove.na from the calling function.

Value

• table
  a 15-element vector containing summary statistics, see below:
• [1]
  the sample size, N.
• [2]
  the number of NAs removed from the data passed for processing.
• [3:7]
  the minimum value, Q1, Median, Q3 and maximum value.
• [8]
  the Median Absolute Deviation (MAD).
• [9]
  the Inter-Quartile Standard Deviation (IQSD).
• The contents of elements [10:15] depend on the value of log
• [10]
  the data (sample) Mean.
• [11]
  the data (sample) Standard Deviation (SD).
• [12]
  the Coefficient of Variation as a percentage (CV%).
• [13]
  the Standard Error (S.E.) of the Mean.
• [14]
  the Lower 95% Confidence Limit on the Mean.
• [15]
  the Upper 95% Confidence Limit on the Mean.
• If log = TRUE, the results for the mean, [13], and confidence limits, [14:15], are backtransformed to the natural scale. The returned table is rounded to 4 significant figures.
