permutation p-values should never be zero: calculating exact p-values when permutations are randomly drawn
Permutation P-values should never be zero: calculating exact P-values when permutations are randomly drawn
This is a research paper whose authors are Belinda Phipson , Gordon K Smyth,
Abstract:
Permutation tests are among the most extensively used statistical procedures in current genomic research, and they include randomly permuting the sample or gene labels to assign p-values to test statistics. However, permutation p-values reported in the genomic literature are frequently estimated improperly, understating the number of permutations by roughly 1/m. When Monte Carlo simulation is used to assign p-values, the same thing frequently happens. Although the p-value understatement is generally small in absolute terms, the repercussions in a multiple testing situation might be severe.The underestimation stems from the intuitive but incorrect notion of using permutation to estimate the tail probability of the test statistic. Instead, we propose that permutation should be understood as yielding an exact discrete null distribution. The relevant literature, some of which is likely to have been relatively unavailable to the genetic community, is reviewed and summarised.Conclusions:
When permutations are selected at random, a computing approach is established for accurate p-values. The approach works for any number of permutations and samples. Some basic guidelines are offered for the practical application of permutation testing.To learn more about statistics, visit :

Aiyana draws figures JKLM and PQRS on the grid.
PART A Aiyana dilates figure JKLM to form image JK'L'M'. She uses a scale
factor of 1 and point J as the center of dilation. How are the original figure and
its image related?
(I also need help placing JK’L’M’
The relationship between the figure JKLM and it's image, J'K'L'M' following a dilation by a scale factor of 1 is that JKLM and J'K'L'M' have the same dimensions, and location
J'K'L'M' should be placed at the same lol as JKLMWhat are scale factors?Scale factors are numbers that are used to multiply a quantity to scale it by a given rate.
Part A
In order to easily describe the relationship between the image J'K'L'M' and the original figure JKLM, the point J can be taken as the origin such that the image vertices are obtained by dilating the points on the original figure in their original direction relative to J using the specified scale factor.
The coordinates of the vertices of JKLM relative to J are;
J(0, 0), K(6, 0), L(6, -6), M(0, -6)
Distance of K from J = 6 - 0 = 6 units to the right of K
Therefore, using a scale factor of 1;
Distance of K' from J = 1 × 6 units = 6 units to the rightThe distances of the vertices of square J'K'L'M' from point J are the same and in the same direction as the distances of the vertices of square JKLM from point J.
JKLM and J'K'L'M' have the same dimensions following the dilation of JKLM by a scale factor of 1The vertices of J'K'L'M' using a scale factor of 1 are therefore located at the same coordinates as the vertices of square JKLM
J'K'L'M' should therefore placed in the same location as JKLMLearn more about drawing scale factors here:

HELP, find the domain.
the domain of the graphed function is D: [-5, 3]
How to identify the domain of the function?
For a function f(x), we define the domain as the set of the inputs of the function.
So, to identify the domain, we need to look a the horizontal axis.
Doing that, we can see that the first value in the horizontal axis is x = -5, and the last value is x = 3.
Notice that in both cases we have solid dots, which means that these values do belong to the domain.
Then the domain of the graphed function is D: [-5, 3]

1) 72 + 18 =90. Therefore the angles are complementary angles
2) Angles one and two are a pair of opposite angles made by two intersecting lines. Those are called vertical angles.
3) Those two are right angles, and two right angles add up to 180. So they are right angles and supplementary angles.
4) Adjacent angles
5) Vertical angles and supplementary (because both are right angles)
6) Right angles, supplementary, linear, adjacent angles.
7) Complementary and adjacent angles.
8) Angle of a straight line is 180. So 180-21 should equal x. x=159
9) As stated in number 2, vertical angles are congruent. x=129
10) 38 and x are complementary angles. (it shows a box on the angle formed by both of them, which means it is a right angle.) 90-38 = 52
11) Vertical angle rule. y = 93. The sum of 93, y, x, and z is 360, because the degree of a full circle is 360 degrees. so, 360-93-93 is 174. However, because of the vertical angle rule we will know that x=z. so 174/2 is 87.
x=87 and z=87
12) If you read the question, it states m∠PQR is 147, and ∠PQR is consisted of 119 and x. So, 147-119 is x. x=28
13) W and 34 are linear angles. Linear angles add up to 180 degrees. So, 180-34. w=146. Angle x is labeled with a box at the vertex of the angle. That indicates it is a right angle. x=90. The angle formed with 34 and z is labeled with a box at the vertex, indicating 34+z is 90. Therefore, 90-34=z. z=56. Finally, because angle x is linear with angle (y+z), we will know that y+z is equal to 90. Therefore, y+z=90, y+56=90, y=90-56, y=34
14) We are given that m∠AEC is 41. ∠AEC and ∠AED are linear angles. So, m∠AED = 180-41. m∠AEC=139
15) ∠DEF is a right angle, indicated by the box label at the vertex. ∠DEF and ∠CEF are linear angles, therefore m∠CEF = 180-90. m∠CEF=90
16) ∠DEB and ∠AEC are vertical angles. Therefore m∠AEC and m∠DEB are equal. ∠DEB=41
17) ∠DEB and ∠BEF form a right angle together. In question 16 we confirmed that m∠DEB is 41. Therefore m∠BEF is equal to 90-41.
m∠BEF=49
18) In question 15 we confirmed that m∠CEF is 90, and in question 17 we confirmed that m∠BEF is 49. So m∠CEB must be 90+49. m∠CEB=139
19) In question 15 we confirmed that m∠CEF is 90, and the direction states m∠AEC is 41. Therefore m∠AEF is 90+41. m∠AEF=131
20) Vertical angles are congruent. Therefore ∠PQR is the same degree measure as ∠SQT. m∠PQR=109
21) Complementary angles add up to 90. Therefore ∠2+∠3 = 90. And it is given that ∠2=24. Therefore ∠3 = 90-24. ∠3=66
22) Supplementary angles add up to 180. Therefore ∠K+∠L= 180. And it is given that ∠K=56. Therefore ∠L = 180-56. ∠L=124
question add 113 (−56) using the number line. select the location on the number line to plot the sum.

A simple random sample is a subset of a statistical population in which each member of the subset has an equal probability of being chosen. A simple random sample is meant to be an unbiased representation of a group.
Random sampling, or probability sampling, is a sampling method that allows for the randomization of sample selection, i.e., each sample has the same probability as other samples to be selected to serve as a representation of an entire population.
Simple random sampling is the randomized selection of a small segment of individuals or members of a whole population. It provides each individual or member of a population with an equal and fair probability of being chosen. The simple random sampling method is one of the most convenient and simple sample selection techniques.
Simple random samples are determined by assigning sequential values to each item within a population, then randomly selecting those values.

B is the midpoint of AC and E is the midpoint of BD. If A(-9, -4), C(-1, 6), and E(-4, -3), find the coordinates or D
The coordinates of point D is (- 3, - 7).
How to determine the coordinates of a endpoint of a line segment divided by a midpoint
A midpoint is a point that partitions a line segment in two parts of equal length. First, we must find the coordinates of point B by using the midpoint formula:
B(x, y) = 0.5 · A(x, y) + 0.5 · C(x, y)
B(x, y) = 0.5 · (- 9, - 4) + 0.5 · (- 1, 6)
B(x, y) = (- 4.5, - 2) + (- 0.5, 3)
B(x, y) = (- 5, 1)
And the location of point D is found by using the midpoint formula again:
E(x, y) = 0.5 · B(x, y) + 0.5 · D(x, y)
(- 4, - 3) = 0.5 · (- 5, 1) + 0.5 · D(x, y)
(- 4, - 3) = (- 2.5, 0.5) + 0.5 · D(x, y)
(- 8, - 6) = (- 5, 1) + D(x, y)
D(x, y) = (- 8, - 6) - (- 5, 1)
D(x, y) = (- 3, - 7)
