I have an old Samsung ML-2010 that has obtained a strange problem. When printing a PDF, image, or from chromium what is suppose to be black and white is inverted. In order to print an image, I had to use GIMP to invert the colors. Printing the image with inverted colors caused the image to be... (2 Replies)
I have a simple gnuplot question. I have a set of points (list of x,y,z values; irregularly spaced, i.e. no grid) that I want to plot. I want the plot to look like this:
- map view (no 3D view)
- color of each point should depend on z-value.
- I want to define my own color scale
- plot should... (1 Reply)

MINISTAT(1) BSD General Commands Manual MINISTAT(1)NAME
ministat -- statistics utility
SYNOPSIS
ministat [-ns] [-C column] [-c confidence_level] [-d delimiter] [-w [width]] [file ...]
DESCRIPTION
The ministat command calculates fundamental statistical properties of numeric data in the specified files or, if no file is specified, stan-
dard input.
The options are as follows:
-n Just report the raw statistics of the input, suppress the ASCII-art plot and the relative comparisons.
-s Print the average/median/stddev bars on separate lines in the ASCII-art plot, to avoid overlap.
-C column Specify which column of data to use. By default the first column in the input file(s) are used.
-c confidence_level
Specify desired confidence level for Student's T analysis. Possible values are 80, 90, 95, 98, 99 and 99.5 %
-d delimiter
Specifies the column delimiter characters, default is SPACE and TAB. See strtok(3) for details.
-w width Width of ASCII-art plot in characters, default is 74.
A sample output could look like this:
$ ministat -s -w 60 iguana chameleon
x iguana
+ chameleon
+------------------------------------------------------------+
|x * x * + + x +|
| |________M______A_______________| |
| |________________M__A___________________| |
+------------------------------------------------------------+
N Min Max Median Avg Stddev
x 7 50 750 200 300 238.04761
+ 5 150 930 500 540 299.08193
No difference proven at 95.0% confidence
If ministat tells you, as in the example above, that there is no difference proven at 95% confidence, the two data sets you gave it are for
all statistical purposes identical.
You have the option of lowering your standards by specifying a lower confidence level:
$ ministat -s -w 60 -c 80 iguana chameleon
x iguana
+ chameleon
+------------------------------------------------------------+
|x * x * + + x +|
| |________M______A_______________| |
| |________________M__A___________________| |
+------------------------------------------------------------+
N Min Max Median Avg Stddev
x 7 50 750 200 300 238.04761
+ 5 150 930 500 540 299.08193
Difference at 80.0% confidence
240 +/- 212.215
80% +/- 70.7384%
(Student's t, pooled s = 264.159)
But a lower standard does not make your data any better, and the example is only included here to show the format of the output when a sta-
tistical difference is proven according to Student's T method.

HISTORY
The ministat command was written by Poul-Henning Kamp out of frustration over all the bogus benchmark claims made by people with no under-
standing of the importance of uncertainty and statistics.
From FreeBSD 5.2 it has lived in the source tree as a developer tool, graduating to the installed system from FreeBSD 8.0.
