Welcome guys in this video I will present a comprehensive analysis of my top picks from EV industry. I will also guide you on how you can lock your profits at higher levels instead of watching them turning to losses from massive unrealized gains and will also discuss how to avoid getting stuck at higher levels. Because EV stocks are volatile and our purpose is to make money not to get attached with any stock. Stock market is huge and provides many opportunities.

This Time Series Analysis (Part-2) in R tutorial will help you understand what is ARIMA model, what is correlation & auto-correlation and you will alose see a use case implementation in which we forecast sales of air-tickets using ARIMA and at the end, we will also how to validate a model using Ljung-Box text.

A time series is a sequence of data being recorded at specific time intervals. The past values are analyzed to forecast a future which is time-dependent. Compared to other forecast algorithms, with time series we deal with a single variable which is dependent on time. So, lets deep dive into this video and understand what is time series and how to implement time series using R.
Below topics are explained in this “ Time Series in R Tutorial “ –
1. Introduction to ARIMA model
2. Auto-correlation & partial auto-correlation
3. Use case – Forecast the sales of air-tickets using ARIMA
4. Model validating using Ljung-Box test

Build a Artificial Neural Network (ANN) with Long-Short Term Memory (LSTM) to predict value which can be impacted by multiple different features.
In this video I demonstrate how to use LSTM to predict Google Stock price (you can use any other case) by taking into consideration multiple predictors (features). Let’s say, the final stock price can be predicted by finding importance of such features as historical low price, high price, volume, adj. price, etc.

The video has 3 parts:
– Part 01. Data pre-processing (4:11)
| Step 01: Read data.
| Step 02: Data pre-processing (shaping and transformations).
– Part 02. Create a LSTM model and train it. (10:39)
| Step 03: Building-up the LSTM based Neural Network.
| Step 04: Start training.
– Part 03. Make future predictions. (13:50)
| Step 05: Make predictions for future date.
| Step 06: Visualize the predictions.
In this tutorial I used Tensorflow 1.15.0 and Keras 2.3.1
Download data from: https://finance.yahoo.com/quote/GOOG/history (check 1:59 in video).
This is real life Python code example for demonstration purposes, so the model is not very accuracy and of course could be improved or tuned.
My goal of this Python tutorial is to demonstrate how to perform LSTM predictions with multiple features (complex dataset).
Hoping it will help to undersant the way it could be implemented in real Data Science or Data Analysis projects. TIme Series forecasting with LSTM is the good choice if you want to manipulate with multiple different data features and see which ones has impact to predictions and which ones do not.

Creating a time series forecast when the series has a trend. Use excel’s „slope“ and „intercept“ commands to estimate the equation for a line and use it to forecast future values. Create a historical forecast using the line and compare it to actual data to evaluate the likely precision of your forecast.
