Topics
MedCalc Confidence: 91% Arrow up

MedCalc is a statistical software package designed for the biomedical sciences.

It has an integrated spreadsheet for data input and can import files in several formats (Excel, SPSS, CSV).

Receiver operating characteristic Confidence: 87% Arrow up

In statistics, a receiver operating characteristic curve, or ROC curve, is a graphical plot that illustrates the performance of a binary classifier system as its discrimination threshold is varied.

The curve is created by plotting the true positive rate (TPR) against the false positive rate (FPR) at various threshold settings.

The true-positive rate is also known as sensitivity, recall or probability of detection in machine learning.

The false-positive rate is also known as the fall-out or probability of false alarm and can be calculated as (1 − specificity).

The ROC curve is thus the sensitivity as a function of fall-out.

In general, if the probability distributions for both detection and false alarm are known, the ROC curve can be generated by plotting the cumulative distribution function (area under the probability distribution from to the discrimination threshold) of the detection probability in the y-axis versus the cumulative distribution function of the false-alarm probability on the x-axis.

Quality control Confidence: 78% Arrow up

Quality control, or QC for short, is a process by which entities review the quality of all factors involved in production.

ISO 9000 defines quality control as "A part of quality management focused on fulfilling quality requirements".

Statistics Confidence: 76% Arrow up

Statistics is a branch of mathematics dealing with the collection, analysis, interpretation, presentation, and organization of data.

In applying statistics to, e.g., a scientific, industrial, or social problem, it is conventional to begin with a statistical population or a statistical model process to be studied.

Populations can be diverse topics such as "all people living in a country" or "every atom composing a crystal".

Statistics deals with all aspects of data including the planning of data collection in terms of the design of surveys and experiments.

Medical research Confidence: 75% Arrow up

Biomedical research (or experimental medicine) is in general simply known as medical research.

It is the basic research (also called bench science or bench research), applied research, or translational research conducted to aid and support the development of knowledge in the field of medicine.
