Quantifying and Rejecting Outliers: The Grubbs Test01:02

Quantifying and Rejecting Outliers: The Grubbs Test

4.6K
Sometimes, a data set can have a recorded numerical observation that greatly  deviates from the rest of the data. Assuming that the data is normally distributed, a statistical method called the Grubbs test can be used to determine whether the observation is truly an outlier.  To perform a two-tailed Grubbs test, first, calculate the absolute difference between the outlier and the mean. Then, calculate the ratio between this difference and the standard deviation of the sample. This...

Mutation, Gene Flow, and Genetic Drift

65.9K
In a population that is not at Hardy-Weinberg equilibrium, the frequency of alleles changes over time. Therefore, any deviations from the five conditions of Hardy-Weinberg equilibrium can alter the genetic variation of a given population. Conditions that change the genetic variability of a population include mutations, natural selection, non-random mating, gene flow, and genetic drift (small population size).

Genetic Variation01:25

Genetic Variation

1.6K
Genetic variation is the diversity in DNA sequences found among individuals of the same species. This diversity is crucial for a species' survival because it helps organisms adapt to environmental changes. Genetic variation begins with fertilization, where an egg and sperm cell merge. Each of these cells carries 23 chromosomes, up to 46 in the fertilized egg. Chromosomes are long DNA strands that contain genes, the basic units of heredity.
Genes exist in different versions called alleles,...

Expected Frequencies in Goodness-of-Fit Tests

8.9K
A goodness-of-fit test is conducted to determine whether the observed frequency values are statistically similar to the frequencies expected for the dataset. Suppose the expected frequencies for a dataset are equal such as when predicting the frequency of any number appearing when casting a die. In that case, the expected frequency is the ratio of the total number of observations (n)  to the number of categories (k).

Hardy-Weinberg Principle01:49

Hardy-Weinberg Principle

77.4K
Diploid organisms have two alleles of each gene, one from each parent, in their somatic cells. Therefore, each individual contributes two alleles to the gene pool of the population. The gene pool of a population is the sum of every allele of all genes within that population and has some degree of variation. Genetic variation is typically expressed as a relative frequency, which is the percentage of the total population that has a given allele, genotype or phenotype.

    Area of Science:

    • Genomics
    • Bioinformatics
    • Computational Biology

    Background:

    • Selecting functional gene subsets is critical for drug discovery and personalized medicine.
    • Simple selection of top individual genes can lead to redundant combinations and suboptimal performance.

    Purpose of the Study:

    • To develop a novel method for selecting gene subsets based on minimum Bayesian error probability.
    • To identify gene combinations that are both individually discriminative and collectively informative for cancer classification.

    Main Methods:

    • A dynamic gene evaluation approach that selects one gene at a time.
    • Genes are selected if they enhance classification information when combined with previously selected genes.
    • The criterion used is the minimization of Bayesian error probability.

    Main Results:

    • The proposed method effectively sifts gene subsets with high discriminative power.
    • Classifiers built using these gene subsets achieve high accuracy in cancer classification.
    • The selected genes are likely to be functionally related, reflecting biological co-regulation.

    Conclusions:

    • The minimum Bayesian error probability criterion offers a robust approach for functional gene subset selection.
    • This method enhances cancer classification accuracy while reducing the number of genes required.
    • The findings support the application of this method in drug discovery and patient-tailored therapies.
