Abstract

This individual's Keystrokes is generally 16.85% higher than normal after an average of 0.2 count Lifting Weights over the previous 7 days. This individual's data suggests with a high degree of confidence (p=0.12218653076508, 95% CI -2202.72 to 2202.894) that Lifting Weights has a very weakly positive predictive relationship (R=0.09) with Keystrokes. The highest quartile of Keystrokes measurements were observed following an average 0.17 count Lifting Weights. The lowest quartile of Keystrokes measurements were observed following an average 0.16724761904762 count Lifting Weights.Keystrokes is generally 6.74% lower than normal after an average of 0.16724761904762 count of Lifting Weights over the previous 7 days. Keystrokes is generally 16.85% higher after an average of 0.17 count of Lifting Weights over the previous 7 days.

Objective

The objective of this study is to determine the nature of the relationship (if any) between Lifting Weights and Keystrokes. Additionally, we attempt to determine the Lifting Weights values most likely to produce optimal Keystrokes values.

Design

This study is based on data donated by one participant. Thus, the study design is consistent with an n=1 observational natural experiment.

Data Analysis

Lifting Weights Pre-Processing
Lifting Weights measurement values below 0 count were assumed erroneous and removed. No maximum allowed measurement value was defined for Lifting Weights. It was assumed that any gaps in Lifting Weights data were unrecorded 0 count measurement values.
Lifting Weights Analysis Settings

Keystrokes Pre-Processing
Keystrokes measurement values below 1 event were assumed erroneous and removed. No maximum allowed measurement value was defined for Keystrokes. No missing data filling value was defined for Keystrokes so any gaps in data were just not analyzed instead of assuming zero values for those times.
Keystrokes Analysis Settings

Predictive Analytics
It was assumed that 0 hours would pass before a change in Lifting Weights would produce an observable change in Keystrokes. It was assumed that Lifting Weights could produce an observable change in Keystrokes for as much as 7 days after the stimulus event.

Data Quantity
902 raw Lifting Weights measurements with 300 changes spanning 1263 days from 2016-01-14 to 2019-06-30 were used in this analysis. 2118 raw Keystrokes measurements with 715 changes spanning 2018 days from 2013-11-26 to 2019-06-07 were used in this analysis.

Data Sources

Lifting Weights 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.

Keystrokes data was primarily collected using WhatPulse. WhatPulse is a small application that measures your keyboard/mouse usage, down- & uploads and your uptime. It sends these statistics here, to the website, where you can use these stats to analyze your computing life, compete against or with your friends and compare your statistics to other people.

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.

The list of the criteria is as follows:
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 very weakly positive relationship between Lifting Weights and Keystrokes

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. 539 paired data points were used in this analysis. Assuming that the relationship is merely coincidental, as the participant independently modifies their Lifting Weights 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, 1 humans feel that there is a plausible mechanism of action and 0 feel that any relationship observed between Lifting Weights and Keystrokes 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.
