Data Analysis: My End-to-End Approach

by

Introduction Have you ever been given a set of data files, asked to clean, model, analyze, and visualize them? This is a post on doing exactly that type of data analysis. Together, we are going to complete this objective, step-by-step. The goal is to understand how to properly analyze datasets in a methodical way. We … Read more

Introduction Time-series analysis is a powerful way to predict events that occur at a future time. In this post I am going to be following up from three previous posts (Pt 1 –> https://rebrand.ly/l1tf4p1, Pt 2 -> https://rebrand.ly/zjgpw8v and Introduction to Time-Series –> https://rebrand.ly/z4lomwu). In Pt 2, I used a dummy dataset to show how to create an ARIMA … Read more

Let’s say you want to forecast future revenue. You could fill in a month-to-month or week-to-week spreadsheet template. However, these are very subjective methods of trying to predict the future and often wildly inaccurate.

A better method would be to create predictive models using time series analysis. Time series predictive models are a specific subset of statistical models that deal with data that are ordered by and dependent on time. On a graph, the x-axis would be time, with the y-axis the thing (revenue, in this case) you are measuring.

In this post, I will give an overview of one type of time series models and describe how they work in simple language. I will describe how to implement the models in BigQuery ML.
