A whys gent being fascinated by people, math, data, art, code, seeks liberation by the Medium of writing...

I have given a live webinar on this topic here with Mathematical Spaces.

You can watch it here for a better impact.

I am an edupreneur.

I am happy.

This article is all about the theory and the practical steps in becoming a happy edupreneur.

An entrepreneur, who works in the education domain.

An entrepreneur is someone, who

- Solves a problem in society and, adds value to the society.
- Builds a proper team for the goal, and creates
**employment opportunities.** - Makes a dedicated process towards the growth of the product and the team.

To impact the lives of the…

In the first part of this series, I have discussed the following questions.

- What is Time Series?
- What is the main focus of Time Series?
- How is Time Series different from Regression?
- How to mathematically model Time Series?
- Why stationarity of the Time Series?
- What is the Central Idea (the two fundamental steps)?
- What is ARIMA modeling in short?

`Exploratory Data Analysis and Transform data into stationary data.`

`Model and Predict the dependence structure of the errors.`

I will discuss the following questions:

- What is stationary data?
- What are the components behind prediction?
- How future data depend on the past…

In terms of probability, X is called a random variable.

`data = read.csv("location/filename.csv")`

`head(data) `

tail(data)

`str(data)`

- PercentOfBaseline

- Date
- AirportName
- Centroid (of airports)
- City
- State
- Country
- Geography (of countries)

- This is time-series data.
- The centroid and geography will be only helpful if we want to visualize the data on the world map.
- Country → State → City → AirportName are factor variables inside the next one.

- Data Visualization is the main focus of the project.
- Due to the structure of Country → State → City → AirportName, the best way to visualize it in an app with dropdown options. (R Shiny App, Tableau, Power BI, etc.)

Time Series is a specific data structure in R.

We have to convert data into time series data structures to apply time series algorithms.

`library(dplyr)`

data_chile = data %>% filter(Country == "Chile")

chile = data_chile[,c(2,5)]

head(chile)

- 1,2,3,4,… as time index with no NA values.

`library(zoo)`

z <- read.zoo(chile, format = "%Y-%m-%d")#zoo series for dates

time(z) <- seq_along(time(z))#sequential data as 1,2,3,4,...

ts_chile = as.ts(z) #conversion into time series data structure

head(ts_chile)

- Date as a time index with NA values to be removed.

`library(zoo)`

library(tseries)#for removing na from ts()

z <- read.zoo(chile, format = "%Y-%m-%d")#zoo series for dates

ts_chile =…

`str(data)`

**PercentofBaseline**

**Date**- City (inside State)
- State (inside Country)
**Country (We will focus on this important Categorical Factor)**- Airport Name (inside City)

We don’t know if we have information about all the airports, cities of the four countries. Thus, the movement of PecentofBaseline only matters along time in each of the different airports, cities, and countries given.

**Kernel Density of PercentofBaseline**

`ggplot(data, aes(x = PercentOfBaseline, fill = "red"))+geom_density(alpha = 0.2)`

The first question, that must come to any sane person’s mind, unlike me is that

“Why do we need to seek liberation?”

- Take a long breath slowly.
- Hold the breath for 5–10 seconds.
- Then release, exhale focusing on the breath slowly
- Try to feel and experience the breath movement.

**Go ahead. Do this. Come back, and then start reading.**

Hey, you came back.

Do you feel like doing it once again?

Who am I to stop you? :p

Rate the feeling of the following three based on your experience.

- When you inhaled?
- When you kept the breath inside you?
- When…

Being a math student, I have always asked myself the question

“What is the meaning of equation x = y with respect to life?”

By the way, how to ask the right questions will be the new intellectual power in the 21st century. Let’s keep that for a different blog post.

Yes, so coming back to x =y, I realized a lot. Not only, I did find it everywhere, but according to the spiritual aspect of a human being, this is the first truth.

Oh! “How to find the truth?” …

**Flow State** comes at a cost. Are you ready for it?

Just for one moment in your life, you must have been in that state, if you are properly fed (not overfed) and rested.

It comes irrespective of caste, creed, gender, money, and all other walls in human society.

All of us want to be in that flow state always, immersed, absorbed, and focused at that moment.

What is the Flow State?

Let me give an analogy. It is like driving a car at the full speed. It is like traveling the world, sitting on an electron. It feels blissful…

I was meditating. Instead of being calm, I felt stressed out, irritated, and out of control. What exactly happened? How to avoid this?

To understand this, you have to understand the dynamics of stress.

Stress is good. But how much? Stress is all about imbalance. Imbalance of what?

Carry heavy luggage with your forearms for a certain period of time. It is bearable initially. Then just after a certain time point, it breaks down. You have to let go of that luggage. Your forearms are stressed out.

What causes discomfort?

An imbalance of the chemicals in the muscles. …
