Abstract

This individual's Efficiency Score From Rescuetime is generally 0.27% higher than normal after a total of 4 minutes Peak Heart Rate Zone over the previous 24 hours. This individual's data suggests with a high degree of confidence (p=0.34998621040489, 95% CI -0.943 to 0.935) that Peak Heart Rate Zone Minutes has a very weakly negative predictive relationship (R=0) with Efficiency Score From Rescuetime. The highest quartile of Efficiency Score From Rescuetime measurements were observed following an average 4 minutes Peak Heart Rate Zone Minutes per day. The lowest quartile of Efficiency Score From Rescuetime measurements were observed following an average 4.3255813953488 min Peak Heart Rate Zone Minutes per day.Efficiency Score From Rescuetime is generally 0.08% lower than normal after a total of 4 minutes of Peak Heart Rate Zone over the previous 24 hours. Efficiency Score From Rescuetime is generally 0.27% higher after a total of 4 minutes of Peak Heart Rate Zone over the previous 24 hours.

Objective

The objective of this study is to determine the nature of the relationship (if any) between Peak Heart Rate Zone Minutes and Efficiency Score From Rescuetime. Additionally, we attempt to determine the Peak Heart Rate Zone Minutes values most likely to produce optimal Efficiency Score From Rescuetime 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

Peak Heart Rate Zone Pre-Processing
Peak Heart Rate Zone measurement values below 0 seconds were assumed erroneous and removed. Peak Heart Rate Zone measurement values above 7 days were assumed erroneous and removed. It was assumed that any gaps in Peak Heart Rate Zone data were unrecorded 0 seconds measurement values.
Peak Heart Rate Zone Analysis Settings

Efficiency Score From Rescuetime Pre-Processing
No minimum allowed measurement value was defined for Efficiency Score From Rescuetime. No maximum allowed measurement value was defined for Efficiency Score From Rescuetime. No missing data filling value was defined for Efficiency Score From Rescuetime so any gaps in data were just not analyzed instead of assuming zero values for those times.

Predictive Analytics
It was assumed that 0 hours would pass before a change in Peak Heart Rate Zone Minutes would produce an observable change in Efficiency Score From Rescuetime. It was assumed that Peak Heart Rate Zone Minutes could produce an observable change in Efficiency Score From Rescuetime for as much as 1 days after the stimulus event.
Predictive Analysis Settings

Data Quantity
504 raw Peak Heart Rate Zone Minutes measurements with 708 changes spanning 1465 days from 2015-03-30 to 2019-04-03 were used in this analysis. 1710 raw Efficiency Score From Rescuetime measurements with 1707 changes spanning 1711 days from 2013-08-10 to 2018-04-17 were used in this analysis.

Data Sources

Peak Heart Rate Zone Minutes data was primarily collected using Fitbit. Fitbit makes activity tracking easy and automatic.

Efficiency Score From Rescuetime data was primarily collected using RescueTime. Detailed reports show which applications and websites you spent time on. Activities are automatically grouped into pre-defined categories with built-in productivity scores covering thousands of websites and applications. You can customize categories and productivity scores to meet your needs.

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 negative relationship between Peak Heart Rate Zone and Efficiency Score From Rescuetime

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. 1145 paired data points were used in this analysis. Assuming that the relationship is merely coincidental, as the participant independently modifies their Peak Heart Rate Zone 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 Peak Heart Rate Zone and Efficiency Score From Rescuetime 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.

Potential Issues Identified During Analysis
The average of effect values expected to be lower than average (83.497383073497) are actually higher than the average (83.434384279476). This suggests a weak relationship or insufficient data.
The average of effect values expected to be higher than average (83.205344129555) are actually lower than the average (83.434384279476). This suggests a weak relationship or insufficient data.
The low effect change is greater than the high effect change.
