Question

How Baltic herring and salmon are used as human food in Baltic sea countries? Which determinants affect on people’s eating habits of these fish species?

Answer

Rationale

Survey of eating habits of Baltic herring and salmon in Denmark, Estonia, Finland and Sweden has been done in September 2016 by Taloustutkimus oy. Content of the questionnaire can be accessed in Google drive. The actual data will be uploaded to Opasnet base on Octobere 2016.

The R-code to analyse the survey data will be provided on this page later on.

Data

Original datafile File:Goherr fish consumption.csv

Preprocessing

This code is used to preprocess the original questionnaire data from the above .csv file and to store the data as a usable variable to Opasnet base.

Analyses

Error creating thumbnail: Unable to save thumbnail to destination

Correlation matrix of all questions in the survey (answers converted to numbers).

Model must contain predictors such as country, gender, age etc. Maybe we should first study what determinants are important? Model must also contain determinants that would increase or decrease fish consumption. This should be conditional on the current consumption. How? Maybe we should look at principal coordinates analysis with all questions to see how they behave.

Also look at correlation table to see clusters.

Some obvious results:

If reports no fish eating, many subsequent answers are NA.
No vitamins correlates negatively with vitamin intake.
Unknown salmon correlates negatively with the types of salmon eaten.
Different age categories correlate with each other.

However, there are also meaningful negative correlations:

Country vs allergy
Country vs Norwegian salmon and Rainbow trout
Country vs not traditional.
Country vs recommendation awareness
Allergy vs economic wellbeing
Baltic salmon use (4 questions) vs Don't like taste and Not used to
All questions between Easy to cook ... Traditional dish

Meaningful positive correlations:

All questions between Baltic salmon ... Rainbow trout
How often Baltic salmon/herring/side salmon/side herring
How much Baltic salmon/herring/side salmon/side herring
Better availability ... Recommendation
All questions between Economic wellbeing...Personal aims
Omega3, Vitamin D, and Other vitamins

# Fish intake in humans
# Data from data.frame survey from page [[Goherr: Fish consumption study]]
# Start with salmon questions 46:49 (amounts eaten)
# Some preprocessing should be moved away from this code.
# Model assumes that questionnaire data follows binomial distribution with parameter p and max value levels.
# p depends on country (4 groups), sex (2), age (2) that are known individually.
# We should test whether sex makes a difference or whether it can be omitted.
# Predicted p for each question, determined by the group, are produced from the bayes model.
# p is used to sample answers, which are then combined with estimates of amounts related to each answer.
# Total amount eaten of each fish per modelled individual is finally calculated.
