Sd line
| Glossary of Statistical Terms |
For a scatterplot, a line that goes through the point of averages, with slope equal to the ratio of the standard deviations of the two plotted variables. if the variable plotted on the horizontal axis is called x and the variable plotted on the vertical axis is called y, the slope of the sd line is the sd of y, divided by the sd of x.

Line, английский
- The basic unit of a frame or field containing the charge, which is proportional to the light falling at various points on the scanning line.
- L
- A report on how well a stranger plays
- Линия
- The correct nautical term for the majority of the cordage or "ropes" used on a vessel. a line will always have a more specific name, such as mizzen topsail halyard, that specifies its use.
- Линь, вер?вка, шнур
- Линь, линия
- The general appellation of a number of small ropes in a ship, as buntlines, clue-lines, bowlines, &c. also, the term in common parlance for the equator. also, in the army, distinguishes the regular numbered regiments of cavalry and infantry from the artillery and guards, to whom exceptional functions are assigned. in fortification, it means a trench, approaches, &c. in a geometrical sense, it signifies length without breadth; and in military parlance, it is drawing up a front of soldiers.—concluding line. a small rope, which is hitched to the middle of every step of a stern-ladder.—deep-sea line. a long line, marked at every five fathoms with small strands of line, knotted, and used with the deep-sea lead. the first 20 fathoms are marked as follows: 2 and 3 fathoms with black leather; 5 with white bunting; 7 with red; 10 with leather and a hole in it. then 13, 15, and 17 repeat the previous marks of 3, 5, and 7. two knots indicate 20, three knots 30, four knots 40 fathoms, and so on, with an additional knot for every ten. meanwhile a single knot indicates the intermediate fives. besides this system some pilots prefer their own marks, as in the hooghly, where they always measure the line for themselves. the term “deep-sea line” must not now be confined to the use of the lead for the ordinary purposes of safe navigation; deep-sea soundings for scientific purposes are recorded in thousands of fathoms, in which case the line is sometimes made of silk, the object being to obtain the largest amount of strength with a small weight.—fishing-lines. particular kinds of lines, generally used for fishing snood, mackerel, whiting, cod, albacore, &c.—hand-line. a line about 20 fathoms long, marked like the first 20 fathoms of the deep-sea line. it is made fast to a hand-lead of from 7 to 14 lbs., and used to determine the depth of water in going in or out of a harbour, river, channel, &c.— hauling-line. any rope let down out of a top, &c., to haul up some light body by hand.—knave-line. a rope fastened to the cross-trees, under the main or fore top, whence it comes down by the ties to the ram-head, and there it is rove through a piece of wood about 2 feet long, and so is brought to the ship`s side, and there hauled up taut to the rails.—life-line. a rope occasionally extended in several situations for persons to lay hold of, to prevent their falling.—mar-line. a particular kind of small line, composed of two strands very little twisted; there is both tarred and white mar-line. that supplied for the gunner and for bending light sails is untarred.—navel-line. a rope depending from the heads of the main and fore masts, and passed round to the bight of the truss to keep it up, whilst the yard is being swayed up, or when the truss, in bracing sharp up, is overhauled to the full.—spilling-lines. ropes fixed occasionally to the square sails, particularly the main and fore courses in bad weather, for reefing or furling them more conveniently; they are rove through blocks upon the yard, whence leading round the sail they are fastened abaft the yard, so that the sail is very closely confined.—white-line. that which has not been tarred, in contradistinction to tarred line.
- [1] is generally defined as being cordage of less than 1-inch (2.5 cm) in circumference. [2] in the usn it refers to rope that has been unspooled and cut for use. [3] one of the dimensions of a convoy, see column. see also braided line.
- Lines. 1. wire and/or fiber ropes and cables. 2. a given direction, bearing, or course.
- To cover the inner surface of. a lined tunnel is a tunnel where
- Гидролиния, магистраль
- A description of the location and grade of a tunnel.
- A continuous mark on a surface, which imparts motion and contour to a design.

Line appearance, английский

Scatterplot, английский
A scatterplot is a way to visualize bivariate data. a scatterplot is a plot of pairs of measurements on a collection of "individuals" (which need not be people). for example, suppose we record the heights and weights of a group of 100 people. the scatterplot of those data would be 100 points. each point represents one person`s height and weight. in a scatterplot of weight against height, the x-coordinate of each point would be height of one person, the y-coordinate of that point would be the weight of the same person. in a scatterplot of height against weight, the x-coordinates would be the weights and the y-coordinates would be the heights.
Horizontal, английский
- Горизонталь; горизонтальный
- Горизонталь; горизонтальный 287
- At right angles to the direction of gravity; on the level; parallel to the horizon; neither vertical nor inclined.
- A direction parallel to the horizon, or what is commonly termed lying flat. one of the greatest inconveniences navigators have to struggle with is the frequent want of a distinct sight of the horizon. to obviate this a horizontal spinning speculum was adopted by mr. lerson, who was lost in the victory man-of-war, in which ship he was sent out to make trial of his instrument. this was afterwards improved by smeaton, and consists of a well-polished metal speculum about 3-1/2 inches in diameter, inclosed within a circular rim of brass, so fitted that the centre of gravity of the whole shall fall near the point on which it spins. this is the end of a steel axis running through the centre of the speculum, above which it finishes in a square for the convenience of fitting a

Graph of averages, английский
For bivariate data, a graph of averages is a plot of the average values of one variable (say y) for small ranges of values of the other variable (say x), against the value of the second variable (x) at the midpoints of the ranges.
De morgan`s laws, английский
De morgan`s laws are identities involving logical operations: the negation of a conjunction is logically equivalent to the disjunction of the negations, and the negation of a disjunction is logically equivalent to the conjunction of the negations. in symbols, !(p & q) = !p | !q and !(p | q) = !p & !q.
