Class: Ratio

A ratio is a relationship between two numbers of the same kind expressed arithmetically as a dimensionless quotient of the two which explicitly indicates how many times the first number contains the second.

Parents

• is_a: DimensionlessQuantity - A dimensionless quantity is a quantity that has no associated unit.

• AspectRatio - The aspect ratio of a geometric shape is the ratio of its sizes in different dimensions.
• DifferentialGeneExpressionRatio - A differential gene expression ratio is the ratio of gene expression values from a test sample compared to a control sample.
• DisGeNETDiseaseSpecificity - DisGeNET Disease specificity is a measure of disease coverage. It is calculated from the negative base 2 log of the ratio of number of diseases associated to the total number of diseases.
• DisGeNETPleiotropyIndex - The DisGeNET pleiotropy index is a measure of specificity as it pertains to classes of disease. The disease pleotropy index is computed from the ratio of the number of disease classes associated with an entity over the total number of disease classes multplied by 100.
• Percentage - A percentage is a number that is a ratio expressed as a fraction of 100. It is denoted using the percent sign "%".
• Slope - A slope or gradient of a line describes its steepness, incline, or grade. A higher slope value indicates a steeper incline. Slope is normally described by the ratio of the "rise" divided by the "run" between two points on a line.
• SpecificGravity - Specific gravity is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume.
• T-statistic - A t-statistic is a ratio of the departure of an estimated parameter from its notional value and its standard error.
