Here I remind you the most common types of nonlinear functions you will find in practice. Most of them will be approached in this section.
An Important Classification of the Nonlinear Relationships4:41
The nonlinear relationships can be divided into two groups: linearizable and non-linearizable. This is important, because the linearizable relationships can be modeled in two ways in SPSS. So let's see what relationships we can found in each group.
Performing a Quadratic Regression in SPSS (1)6:51
In this lecture we are going to run a quadratic regression using the linear regression module in SPSS. In other words, we are going to linearize the quadratic equation before performing the analysis.

We explain how the KNN method works (using a graphicla representation), when it can be used.

It is useful to know both the advantages, as well as the weak points of the decision trees in predictive analysis.

How to interpret the other output provided by SPSS: the tree in table format, the predictor importance chart and the risk (this risk is directly related to the tree prediction accuracy).

Activation Functions3:40
Now it's time to learn about the activation functions that are most widely used in neural networks.

Description

Become a Top Performing Data Analyst – Take This Advanced Data Science Course in SPSS!

Within a few days only you can master some of the most complex data analysis techniques available in the SPSS program. Even if you are not a professional mathematician or statistician, you will understood these techniques perfectly and will be able to apply them in practical, real life situations.

These methods are used every day by data scientists and data miners to make accurate predictions using their raw data. If you want to be a high skilled analyst, you must know them!

Without further ado, let’s see what you are going to learn…

Stepwise regression analysis, a technique that helps you select the best subset of predictors for a regression analysis, when you have a big number of predictors. This way you can create regression models that are both parsimonious and effective.
Nonlinear regression analysis. After finishing this course, you will be able to fit any nonlinear regression model using SPSS.
K nearest neighbor, a very popular predictive technique used mostly for classification purposes. So you will learn how to predict the values of a categorical variable with this method.
Decision trees. We will approach both binary (CART) and non-binary (CHAID) trees. For each of these two types we will consider two cases: the case of response dependent variables (regression trees) and the case of categorical response variables (classification trees).
Neural networks. Artificial neural networks are hot now, since they are a suitable predictive tool in many situations. In SPSS we can train two types of neural network: the multilayer perceptron (MLP) and the radial basis function (RBF) network. We are going to study both of them in detail.
Two-step cluster analysis, an effective grouping procedure that allows us to identify homogeneous groups in our population. It is useful in very many fields like marketing research, medicine (gene research, for example), biology, computer science, social science etc.
Survival analysis. If you have to estimate one of the following: the probable time until a certain event happens, what percentage of your population will suffer the event or which particular circumstances influence the probability that the event happens, than you need to apply on of the survival analysis method studied here: Kaplan-Meier or Cox regression.

For each analysis technique, a short theoretical introduction is provided, in order to familiarize the reader with the fundamental notions and concepts related to that technique. Afterwards, the analysis is executed on a real-life data set and the output is thoroughly explained.

Moreover, for some techniques (KNN, decision trees, neural networks) you will also learn:

How to validate your model on an independent data set, using the validation set approach or the cross-validation
How to save the model and use it for make predictions on new data that may be available in the future.
