Calculating and Interpreting the Linear Correlation Coefficient01:11

Calculating and Interpreting the Linear Correlation Coefficient

8.3K
The correlation coefficient, r, developed by Karl Pearson in the early 1900s, is numerical and provides a measure of strength and direction of the linear association between the independent variable, x, and the dependent variable, y. Hence, it is also known as the Pearson product-moment correlation coefficient. It can be calculated using the following equation:

Correlations

36.3K
Correlation means that there is a relationship between two or more variables (such as ice cream consumption and crime), but this relationship does not necessarily imply cause and effect. When two variables are correlated, it simply means that as one variable changes, so does the other. We can measure correlation by calculating a statistic known as a correlation coefficient. A correlation coefficient is a number from -1 to +1 that indicates the strength and direction of the relationship between...

Correlation and Causation

42.8K
Statistical tests can calculate whether there is a relationship, or correlation, between independent and dependent variables. An indirect relationship of the variables signifies a correlation, while a direct relationship shows causation. If it is determined that no connection exists between the variables, then the correlation is a coincidence.
Correlation versus Causation
If the dependent variable increases or decreases when the independent variable increases, there is a positive or negative...

lncRNA - Long Non-coding RNAs

10.0K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

Correlation

15.2K
In statistics, two variables are said to be correlated if the values of one variable are associated with the other variable. Depending on the relationship between two variables, correlation can be of three types– positive correlation, negative correlation, and zero correlation.
Two variables, for example, a and b, are said to be positively correlated if both variables move in the same direction. In other words, a positive correlation exists between two variables, a and b, if:

    Area of Science:

    • Optics and Photonics
    • Digital Holography
    • Image Reconstruction

    Background:

    • Interferenceless coded aperture correlation holography (I-COACH) is an incoherent digital holography technique.
    • I-COACH uses a pseudorandom coded phase mask (CPM) to modulate object beams for intensity pattern recording.
    • Traditional I-COACH requires multiple recordings, limiting time resolution.

    Purpose of the Study:

    • To develop a non-linear reconstruction technique for I-COACH.
    • To enable image reconstruction from a single camera shot, enhancing time resolution.
    • To create an adaptive method for optimizing parameters in diverse experimental conditions.

    Main Methods:

    • A novel non-linear reconstruction algorithm was developed.
    • The technique was implemented on a standard I-COACH system.
    • Both transmission and reflection illumination modes were utilized.

    Main Results:

    • Successful reconstruction of 3D object images from a single intensity recording.
    • Elimination of bias level and background noise in reconstructions.
    • Demonstration of adaptability to varying experimental parameters.

    Conclusions:

    • The developed non-linear technique significantly improves the time resolution of I-COACH imaging.
    • The method offers an adaptive approach for robust image reconstruction.
    • This advancement broadens the applicability of I-COACH in various illumination modes.
