Basic statistics in Data science
The term “Data science” comes in 1996 which was included in the title of a statistical conference (International Federation of Classification Societies (IFCS). In early 1997, there was an even more
radical view suggesting to rename statistics to Data Science. Recently, “Donoho” provide... | 4 | [

How do you solve $12x + 3 = 6x + 3$?
Hint: The above question is based on the concept of equations having variables on both the sides. The main approach towards solving the problem is to bring the variable on one side i.e., we must add
or subtract from both sides one of the quantities that contains the variable.

Solution:
The given inequality is 3x + 8 > 2
3x + 8 > 2
⇒ 3x + 8 - 8 > 2 - 8
⇒ 3x > - 6
⇒ 3x/3 > - 6/3
⇒ x > - 2
(i) The integers greater than - 2 are - 1, 0, 1, 2, ....
Thus, when x is an integer, the solutions of the given inequality are - 1, 0, 1, 2...

Part A
1. Find the complementary solution by considering the homogeneous equation $y'' - 5y' + 6y = 0$.
Try a solution of the form $y(t) = e^{rt}$. Doing so, we get the characteristic equation:
\begin{align}
r^2 - 5r + 6 = 0 \\
(r-2)(r-3) = 0
\end{align}

Example 64.14.5. Let $C = E$ be an elliptic curve and $\varphi = [n]$ be multiplication by $n$. Then $\varphi ^* = \varphi ^ t$ is multiplication by $n$ on the jacobian, so it has trace $2n$ and
degree $n^2$. On the other hand, the fixed points of $\varphi $ are the points $p \in E$ such that $n p = ... | 4 | [

Strength of Materials/General State of Stress - Wikibooks, open books for an open world
The general state of stress can be represented by a symmetric 3 x 3 matrix.
It is always possible to choose a coordinate system such that all shear stresses are zero. The 3 x 3 matrix is then diagonalised, with the three principal ... | 4 | [

Indirect survey
The usual way to statistically determine the prevalence of a given trait T in a population involves selecting a representative population sample and having their members answer the question "Do you
have trait T?"; the number of affirmative questions divided by the size of the sample is an estimate of th... | 5 | [

Tests for Pairwise Mean Differences in R
Introduction
Inspired by Jonas K. Lindeløv’s excellent website
this post will walk through common statistical tests used when analyzing categorical variables in R.
I’ll cover 5 situations:
1. pairwise differences between members of a category
2. comparison to the overall c... | 5 | [
