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 🥲
2. #Modeltime for time series forecasting

90% of data scientists use R forecast or fable.

These are great.

...if you want to stick to ARIMA...
BUT, what about machine learning?

You know, the algorithms like XGBoost that are winning all the competitions?

Enter Modeltime...
Modeltime not only gives you ARIMA at scale...

But, it gives you XGBOOST + LightGBM + H2O + Tidymodels...

So, it's kinda like comparing a VW Bug 🚗 to a Formula 1 Race Car 🏎️

You get a lot more power outa the box.
Now I know what you're thinking, I need to see it in action BEFORE I give it a try.

Well I have you covered.
I created Timetk, Modeltime, and 5 other time series R packages...

And I'm going to show off what you CAN DO with them in a free workshop...
Join me this Wednesday for a FREE workshop on time series analysis.

You'll leave with everything you need to become the time series expert for your (future) company.

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

A time series thread 🧵

#rstats #excel #python #timeseries Image
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?

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…
