Alcohol Consumpsion - Depression - Age Category

  Analysis of Variance

Introduction

Nesarc dataset is used for alcohol consumption, related age category, and depression data.

Getting Data



In Nesarc dataset, four columns are needed for analysis. 

Consumer: Alcoholic Consumption
Age : Ages
S2AQ4B : How often drank coolers in the last month
Majordeplife: The people who experience depression

Preparing Data


The people who are current and Ex drinkers and their ages between 20 and 50 are filtered for this research.

S2AQ4B (How often drank coolers in the last month) is also recoded as year in a new variable USFREALC. 

Null Hypothesis 1

There is no connection with alcohol consumption and depression.

F Test on Alcohol Consumption and Depression


F-Statistics is really high. 0.706 is higher than 0.05 so we can accept the null hypothesis. "There is no connection with alcohol consumption and depression."

Null Hypothesis 2

There is no connection with alcohol consumption and depression.

F Test on Alcohol Consumption anz    d Age


F-Statistics is really low. so we can reject the null hypothesis. "There is strong connection with alcohol consumption and age."


Means For Alcohol Consumption by Age Category

Standart Deviation For Alcohol Consumption by Age Category
Tucan Test 

The age group 20 - 25 is totaly different group than the others. So we need to reject the null hyptothesis within these groups.

 Logistic Regresion in Nicotine Dependence and Alcohol Dependence Introduction In nesarc data, logisstic regression is analysed with Nicotine Dependence and Alcohol Conumption. People generally tend to smoke cigarettes while consuming alcohol so there might be a relation between the two features. Getting and Preparing Data Both current alcohol consumers (1) and ex-alcohol consumers (2) are filtered. Data Analysis The p-value of CONUMER is less than 0.05, so it is significantly associated with Nicotine Dependence. When the odd ratio is checked, %60 of alcohol consumers are more likely to have nicotine dependency.. Another explanatory variables "Major depression" has been added to mode. It has also low p-value, and it looks like "Major depression" has more association with Nicotine Dependence. Because the odd raition shows that the people have depression has 3.87 times nicotine dependency. Codes "" import numpy import pandas import statsmodels.api as sm ...

CO2 Emissions Corelations

 CO2 Emissions Corelations Introduction I am trying to find out correlation between cumulative CO2 emission (metric tons) and oil Consumption per capita and also cumulative CO2 emission (metric tons) and residential electricity consumption, per person (kWh). Getting Data I have used Gapminder dataset to get the data. Correlations Diagrams Correlation Result In Pearson calculation, there is a slight association between cumulative CO2 emission (metric tons) and residential electricity consumption. That is 0,138. But there is no association  Oil Person which the result is close to 0 which is 0,04.
