No. of samples (cols)

   This is the number of columns in the data set.

No. of zero cells

   This is the number of zero entries in the data matrix.

No. of non zero cells 

This is the number of non zero entries in the data

matrix.

% of zero cells 

This is the number of zero entries divided by the number of

cells in the data matrix.

Maximum value

   This is the maximum value in the data matrix

.

Minimum value

   This is the minimum value in the data matrix.

Range

   This is the difference between the maximum and minimum values.

Mean

To obtain general statistics on the raw data select the Raw Data radio button in

the  Use  panel situated below the grid to select Raw Data.

Statistics for the individual rows and columns of either the raw or working data

matrix are selected using the Statistics radio buttons situated below the grid.

Values for each row or column are shown numbered in the order they appear in

the original data matrix. The statistics calculated are as follows:

Mean

   This is the mean of all the values in the data matrix.

Median

   This is the median of all the values in the data matrix.

Max

   This is the maximum value in the data matrix

.

Min

   This is the minimum value in the data matrix.

Zeros

   This is the number of zero entries in the data matrix.

Non zeros 

This is the number of non zero entries in the data matrix.

% Zeros

   (Number of zeros/Total number of cells) * 100

Sum

   This is the sum of all the values in each row or column in the data matrix.

SumSqr

   This is the sums of squares of all the values in each row or column in

the data matrix.

Variance

   This is the variance of all the values in each row or column in the

data matrix.
