He had used autocorrelation to find crude oil -- who's to say he couldn't use it to nudge a bad singer into tune? Auto-Tune Enters the Music Studio With Auto-Tune, a sound engineer can look at a singer's vocal take and tweak notes that are slightly off key. ©iStockphoto....

It is important to notice that large particles may also originate from poor buffer prepar- ation (all protein purification and storage buffers should systematically be filtered prior to use). Autocorrelation functions can be mathematically resolved using a variety of algorithms, developed either by ...
We then present a formula for the distribution of expected errors as a function of the time horizon and the other parameters of the model, and generalize the formula to allow for autocorrelation in the data generating process. This allows us to pool the errors for many different technologies. ...
The support for time series can be enabled by passing the parametertsmode=true, and the library will automatically identify the presence of features with autocorrelation (more on this later). For the analysis work properly, the dataframe needs to be sorted by entity columns and time, otherwise ...
The time-field detection method involves analyzing the slope, amplitude, and width of the ECG signal to detect ventricular fibrillation (VF). The autocorrelation function (ACF) algorithm then analyzes the periodicities within the ECG signal and uses linear regression to calculate an index called the...
Fit a LOESS curve to the dots Not bad, right? Two lines of code, and you’ve already got your plot. We can do a little better though. Let’s fix it up a bit. Step 3. Modify axis limits It’s usually a good idea to start your values axis at zero if you can. The above grap...
The evaluations of the quality of fit obtained for each analysis and the significance of the parameters were based on four indicators: the χ2 values, the distributions of the residuals, the autocorrelation of the residuals, and the error intervals of the calculated parameters. The quality of ...
