Análisis estadístico Jobs

Statistical analysis is a mathematical science, the practice of evaluating and understanding quantitative data. Statistical analysis will make sense of indexes such as standard deviation, and note outliers. The analysis of the data may aid in decision-making in the face of uncertainty.

Quantitative data is represented as numbers, and therefore may be presented in graph format. This simplifies the explanations and visualizations of the data’s meaning. The graph alone will show a positive or negative correlation, a bell curve, or no correlation at all.

Statistics require a population to be studied, and statistical analysis is commonly used regarding census data organized by governments, sociology and medicine.

Esta variedad en los datos que ingresan y en los documentos que se generan hacen complicado automatizar el proceso con técnicas de programación tradicional. Pensamos que utilizando técnicas de Machine Learning (ML) podemos resolver este reto. La Solución Basados en la metodología de PMV se escoger&aacu...

    It is a study that looks into the knowledge and competance of junior doctors concerning the electrocardiogram (ECG). The ECG is a bed side investigation that can be used to diagnose a wide variety of abnormalities regarding the heart and can give valuable information including life threatening conditions whose management is very time dependent. It is important for medical students to master pattern recognition that can be seen on the ecg and be able to diagnose and manage these conditions appropriately. Having said that, evidence shows that doctors in general are lacking this efficient skill of interpreting the ECG and in addition to that, there is no standard learning curriculum as to which ECG conditions / diagnosis need to be taught to medical students. In this research we use the...

The response, y, is not estimated as a single value, but is assumed to be drawn from a probability distribution. The model for Bayesian Linear Regression with the response sampled from a normal distribution is: The output, y is generated from a normal (Gaussian) Distribution characterized by a mean and variance. The mean for linear regression is the transpose of the weight matrix multiplied by the predictor matrix. The varian...
