Stats Training Materials – Forecasting & Risk Modelling

March 1, 2025 By Nigel Marriott

All organisations want to understand what happened in the past and what will happen in the future. The use of statistics and statistical thinking is essential to be a better forecaster but that doesn’t mean it is easy! At the same time, we are bombarded with forecasts in the media which can make it difficult to decide which forecasts to pay attention to and which can be ignored.

My course “Identifying Trends & Making Forecasts” is all about doing the basics right when it comes to analysing trends and making predictions. To support this course, here are links to material in the public domain covering the following themes:-

Stats Training Materials – Multivariate Analysis

December 31, 2018 By Nigel Marriott

If I were to remark to you that “the weather is very nice today” or “I didn’t like that person”, it is unlikely that I would have made such statements based on a single variable. It is more likely that a combination of variables were evaluated to arrive at these statements. When we analysis datasets with multiple variables, we are undertaking Multivariate Statistical Analysis.

Multivariate Analysis comes in two flavours :-

Analysis of Correlations between Multiple Variables – Known as R-Analysis – Informally known as reducing the dimensionality of your dataset.
Analysis of Distance between Many Objects – Known as Q-Analysis – Informally known as mapping, clustering or segmentation of your dataset.
