TRAINERS FOR COURSE


Details

Performing regressions is a powerful method to help you understand the relationships between your variables, which makes it a must for anyone working with data. Thankfully, we can use the Python language to make this important task much easier and more efficient.

In this course you will learn to: 

  • Perform regressions using Python
  • Analyse the strength of correlations
  • Set conditional expectations
  • Analyse the regression line
  • Employ linear models in real-life scenarios 
  • Understand counfounding
  • Perform Lease Squares Estimates
  • Understand association vs causation

Delivery Methods

Leading Training is focusing on providing virtual training courses for the foreseeable future and will only consider in-person and classroom training on request, with a required minimum group size of four delegates. We remain committed to offering training that is fast, focused and effective.

Regression 

  • Case study: is height hereditary?
  • The correlation coefficient
    • Sample correlation is a random variable
    • Correlation is not always a useful summary
  • Conditional expectations
  • The regression line
    • Regression improves precision
    • Bivariate normal distribution (advanced)
    • Variance explained
    • Warning: there are two regression lines
  • Exercises

Linear models 

  • Case study: Moneyball
    • Sabermetics
    • Baseball basics
    • No awards for BB
    • Base on balls or stolen bases?
    • Regression applied to baseball statistics
  • Confounding
    • Understanding confounding through stratification
    • Multivariate regression
  • Least squares estimates
    • Interpreting linear models
    • Least Squares Estimates (LSE)
    • The lm function
    • LSE are random variables

  • Exercises
  • Linear regression in the tidyverse
    • The broom package
  • Exercises
  • Case study: Moneyball (continued)
    • Adding salary and position information
    • Picking nine players
  • The regression fallacy
  • Measurement error models
  • Exercises

Association is not causation 

  • Spurious correlation
  • Outliers
  • Reversing cause and effect
  • Confounders
    • Example: UC Berkeley admissions
    • Confounding explained graphically
    • Average after stratifying
  •  Simpson’s paradox

Schedule Dates and Booking

There are currently no scheduled dates.

Please note that this course needs a minimum of 6 delegates to schedule a course. You can choose to be added to the waiting list by clicking the button below and we will contact you when we have enough delegates interested. Should we not get enough delegates, we will refund or credit your paid booking.

Add me to the waiting list

Should you need this course urgently, the following options are available:

  1. Pay for 6 delegates (whether you have them or not) and we will schedule the course as soon as possible.
  2. If you have fewer delegates and cannot pay for 6, we can negotiate a shortened course where some of the time will be spent in blended learning - watching videos and doing tutorials and exercises with some contact time with the trainer. We would want to discuss what your core needs are so that we cover those aspects. You need to have paid for 3 delegates at least.
