1、形式不同：quantitative数量上分两种形式：Countinuous连续性的和Discrete非连续性的。qualitative性质上的也分两种：Categorical绝对性的（无先后顺序）和ordinal 顺序的（有先后顺序的）。2、计算方式不同：quantative是需要测量或者数出来的，qualitative是定义的，就像人物的性别不可能超越男，女两种是定义...
A common problem is the question, whether there is a relationship between these categorical outcomes, for example, between the hair color and the eye color. This question is investigated by means of contingency tables. If there is a relationship, then we will try to describe it first by a ...
Question What do these plots tell you about the dangers of extrapolating too much from a model? Is overfitting a possible concern with these tightly fit models?Takeaway Linear regression can be a flexible tool for modeling the relationships between features in our data, particularly with polynomial...
Not all data science tasks can be performed on all data types. For example, the neural network algorithm does not work with categorical data. However, one data type can be converted to another using a type conversion process, but this may be accompanied with possible loss of information. For...
1. For the data in table 1, Question 1. Calculate the ANOVA table for the data. Use the ANOVA Table to conduct an F-Test to see if the model is significant (use alpha = 0.05). 2. Give a 95% confidence What statistical test is used to check if two...
This question was migrated from Stack Overflow because it can be answered on Cross Validated. Migrated 7 days ago. I have some difficulties in thoroughly interpreting all the outcomes of the Poisson Regression Model. I have a Poiss

But also if the data contains factual numbers, this logic will not work: as another example, let's consider the Iris dataset: imagine in one category we have 100 specimens with sepal length 5, and in the other 500 specimens with sepal lenght 1. In both case the sum is 500. So again...
This survey investigates current techniques for representing qualitative data for use as input to neural networks. Techniques for using qualitative data in neural networks are well known. However, researchers continue to discover new variations or entire
Categorical Data Analysis Acategorical variablehas a measurement scale that consists of a set of categories. For example, the response of a student to a test question is often measured as correct or incorrect. Categorical variables have two types of scales – nominal (when the categories do not...
