Hello Everyone, Hope you all are doing good. Today I have come up with a post which would help us to do multivariate variable time series…

Time series forecasting is used in multiple business domains, such as pricing, capacity planning, inventory management, etc. Forecasting with techniques such as ARIMA requires the user to correctly determine and validate the model parameters (p,q,d). This is a multistep process that requires the user to interpret the Autocorrelation Function (ACF) and Partial Autocorrelation (PACF) plots correctly. Using the wrong model can easily lead to erroneous results.

The series of data points plotted against time is known as time series. It is a de-facto analysis technique used in market evaluation and…

Recently we argued that confidence intervals are a poor choice for analyzing staged rollout experiments. In this article, we show a better way: a Bayesian approach that gives decision-makers the answers they really need. Check out our interactive Streamlit app first, then the article for the details.

This is an absolute gem of a book. McElreath has found an elusive combination: Statistical Rethinking is not only one of the best intro textbooks for both causal and Bayesian modeling, it's also highly readable, even entertaining.

Survival analysis has been a standard tool for decades in clinical research, but data scientists in other domains have mostly ignored it. Here are some applications for which you might use survival analysis, to jump-start your creative data science engine.
