When it comes to Time Series, colleges and universities have it all wrong.

A time series thread 🧵

#rstats #excel #python #timeseries
Universities are stuck in the past, teaching ARIMA.

But the cold reality is that ARIMA is NOT winning time series competitions & ARIMA is NOT helping companies solve BIG forecasting problems.
To be frank, ARIMA is too slow.

When you use ARIMA, you fall into a trap. You think, hey, this is what they're teaching me...

It must be good, right?
WRONG!

You end up with commodity performance, which won't help you stand out in your career.
So, I'd love to help you.

I spent 1 year researching time series...

And I lost hope 3 times...

And then I wrote 7 R packages to help...
Now I want to show them off to the world AND help you in the process.

I put together a time series workshop that's free to attend.

Here's what you will learn:
1. What I learned from researching the winning solutions of 4 elite time series competitions

This was eye opening.

Completely the OPPOSITE of what is currently being taught in colleges & universities.
2. Simple changes in my forecasts that made my company 5X more revenue

Small tweaks. Big savings.
3. Which tools have helped me do large scale time series analysis for companies like Walmart & MRM McCann

There's 6 tools I'll share.
4. How I reverse engineered Kaggle solutions to increase my company's profit to $15,000,000 in under 1 year

This is quite a story.
And, as a BONUS, I'm going to be giving away one of my most prized possessions.

It's my 3-page #TimeSeries #Forecasting #CheatSheet.

Anyone can use it to improve their forecasts.

My free gift to you.

Time series analysis is getting...

EASIER!

Here's a quick thread. 🧵

Time series analysis is getting EASIER!

New tools are being developed...
1. #Timetk for time series data wrangling + data viz

Think if this little gold nugget like dplyr + ggplot2 for time series.

Yep, you can slice & dice that time series.

And, get quick visuals that make your boss cry tears of joy 🥲

The most important skill in time series analysis isn’t forecasting.

It’s visualization.

Here's why in this thread. 🧵

#datascience #rstats #excel #timeseries Image
90% of data scientists will model a time series like it’s a machine learning problem.

Apply an algorithm. Tune it. Reduce RMSE.

But I’d argue that visualization will help even more.
Here's how visualization helps.

1. You’ll see the shape of the series.

2. You’ll gain context for the business scenario.

3. And you’ll be able to see whether or not a forecast makes sense.

My #Shiny Web Apps for #Consulting Training (Part 1) was INSANE.

AND I've just made it available for everyone.

Here's how to get it in under 10-seconds.

#rstats #datascience
On Wednesday, 750 data scientists joined me to learn about new R Shiny functionality that makes building apps for clients easer, faster AND better.

And, we talked about how to go from a $1,000 app to a $15,000 app with not a lot of work.
If you want to join in on the FUN, you can check the full training out FOR FREE. My free gift to you.

AND, I have a 2nd part which promises a 100X improvement in shiny app building coming on September 14th!!

Stop learning data science.

Start learning how to solve problems.

Here's how... 🧵

#rstats #python #datascience
Most people dive into learning data science by taking course after course on:

coding,
algorithms,
math,
statistics,
computer science,
APIs,
web apps,
databases,
SQL...
And they learn
R,
Python,
SQL again (advanced this time),
Tableau (because I like dashboards),
PowerBI (because I realized my company doesn’t use tableau),
and…

You get the idea.

What a cluster…
