Participants reported a 3.3% average decrease in Fear following above average Fat Mass Weight.
Abstract

Abstract

Fear was generally 1.075% higher than average after 32.4 kilograms of Fat Mass Weight per 7 days.

Aggregated data from 4 study participants suggests with a MEDIUM degree of confidence (p=0.274, 95% CI -0.543 to 0.301) that Fat Mass Weight has a weakly negative predictive relationship (R=-0.121) with Fear.

The highest quartile of Fear measurements were observed following an average 6.92 kilograms Fat Mass Weight.

The lowest quartile of Fear measurements were observed following an average 7.74 kilograms of Fat Mass Weight.

After an onset delay of 0 seconds, Fear is typically 4% lower than average over the 7 days following around 7.74 kilograms Fat Mass Weight.

Objective

Objective

The objective of this study is to determine the nature of the relationship (if any) between Fat Mass Weight and Fear. Additionally, we attempt to determine the Fat Mass Weight values most likely to produce optimal Fear values.

Design

Design

This study is based on data donated by 4 participants. Thus, the study design is equivalent to the aggregation of 4 separate n=1 observational natural experiments.

Data Analysis

Data Analysis

Fat Mass Weight Pre-Processing

Fat Mass Weight measurement values below 0 kilograms were assumed erroneous and removed. No maximum allowed measurement value was defined for Fat Mass Weight. No missing data filling value was defined for Fat Mass Weight so any gaps in data were just not analyzed instead of assuming zero values for those times.

Fear Pre-Processing

Fear measurement values below 1 out of 5 were assumed erroneous and removed. Fear measurement values above 5 out of 5 were assumed erroneous and removed. No missing data filling value was defined for Fear so any gaps in data were just not analyzed instead of assuming zero values for those times.

Predictive Analytics

It was assumed that 0 seconds would pass before a change in Fat Mass Weight would produce an observable change in Fear.

It was assumed that Fat Mass Weight could produce an observable change in Fear for as much as 7 days after the stimulus event.

Statistical Significance

Statistical Significance

Using a two-tailed t-test with alpha = 0.05, it was determined that the change in Fear is not statistically significant at a 95% confidence interval. This suggests that the Fat Mass Weight value does not have a significant influence on the Fear value.

After treatment, a 3.3% decrease (0.0223 out of 5) from the mean baseline 1.77 out of 5 was observed. The relative standard deviation at baseline was 39.75%. The observed change was 0.299228 times the standard deviation.

A common rule of thumb considers a change greater than twice the baseline standard deviation on two separate pre-post experiments may be considered significant. This occurrence would have only a 5% likelihood of resulting from random fluctuation (a p-value < 0.05).

Data Sources

Data Sources

Fat Mass Weight data was primarily collected using Fitbit. Fitbit makes activity tracking easy and automatic.

Fear data was primarily collected using QuantiModo. QuantiModo allows you to easily track mood, symptoms, or any outcome you want to optimize in a fraction of a second. You can also import your data from over 30 other apps and devices. QuantiModo then analyzes your data to identify which hidden factors are most likely to be influencing your mood or symptoms.

Limitations

Limitations

As with any human experiment, it was impossible to control for all potentially confounding variables. Correlation does not necessarily imply causation. We can never know for sure if one factor is definitely the cause of an outcome. However, lack of correlation definitely implies the lack of a causal relationship. Hence, we can with great confidence rule out non-existent relationships. For instance, if we discover no relationship between mood and an antidepressant this information is just as or even more valuable than the discovery that there is a relationship.

We can also take advantage of several characteristics of time series data from many subjects to infer the likelihood of a causal relationship if we do find a correlational relationship. The criteria for causation are a group of minimal conditions necessary to provide adequate evidence of a causal relationship between an incidence and a possible consequence.

Criteria For Causal Inference

Strength (A.K.A. Effect Size)

A small association does not mean that there is not a causal effect, though the larger the association, the more likely that it is causal. There is a weakly negative (R = -0.121) relationship between Fat Mass Weight and Fear.

Consistency (A.K.A. Reproducibility)

Consistent findings observed by different persons in different places with different samples strengthens the likelihood of an effect. Furthermore, in accordance with the law of large numbers (LLN), the predictive power and accuracy of these results will continually grow over time. 101 paired data points were used in this analysis. Assuming that the relationship is merely coincidental, as the participant independently modifies their Fat Mass Weight values, the observed strength of the relationship will decline until it is below the threshold of significance. To it another way, in the case that we do find a spurious correlation, suggesting that banana intake improves mood for instance, one will likely increase their banana intake. Due to the fact that this correlation is spurious, it is unlikely that you will see a continued and persistent corresponding increase in mood. So over time, the spurious correlation will naturally dissipate.

Specificity

Causation is likely if a very specific population at a specific site and disease with no other likely explanation. The more specific an association between a factor and an effect is, the bigger the probability of a causal relationship.

Temporality

The effect has to occur after the cause (and if there is an expected delay between the cause and expected effect, then the effect must occur after that delay). The confidence in a causal relationship is bolstered by the fact that time-precedence was taken into account in all calculations.

Biological Gradient

Greater exposure should generally lead to greater incidence of the effect. However, in some cases, the mere presence of the factor can trigger the effect. In other cases, an inverse proportion is observed: greater exposure leads to lower incidence.

Plausibility

A plausible bio-chemical mechanism between cause and effect is critical. This is where human brains excel.

Based on our responses so far,

0 humans feel that there is a plausible mechanism of action for a relationship between Fat Mass Weight and Fear.

0 humans feel that any relationship observed between Fat Mass Weight and Fear is coincidental.

Coherence

Coherence between epidemiological and laboratory findings increases the likelihood of an effect. It will be very enlightening to aggregate this data with the data from other participants with similar genetic, diseasomic, environmentomic, and demographic profiles.

Experiment

All of human life can be considered a natural experiment. Occasionally, it is possible to appeal to experimental evidence.

Analogy

The effect of similar factors may be considered.

Plausibility
