Finished up on the summary of linear regression as a form of prep for the fall classes. Currently, the coding part is not that clear to me but it should become easier as I code more.

woo! linear regressions!
I genuinely enjoy doing bad linear regressions as a joke, like predicting something from them that makes zero fucking sense whatsoever
Can't think of an example but I know I've done some funny bullshit before

That's not how demographics work.

Maths and Evolutionary Biology
  Maths and Evolutionary Biology Mathematics is often utilised across many fields – lets look at an example from biology, evolutionary biology and paleontology, in trying to understand the development of homo-sapiens.  We can start with a large data set which gives us the data for mammal body mass and brain size in grams (downloaded from here).  I then tidied up this to remove the rows with NA…

DESCIFRANDO LA RELACIÓN ENTRE INGRESOS Y CONSUMO DE ALCOHOL: EL MISTERIO DEL COEFICIENTE DE CORRELACIÓN DE PEARSON
En esta entrada, exploraremos el coeficiente de correlación de Pearson, centrándonos en la relación entre el ingreso total anual y el consumo total anual estimado de alcohol.
Análisis de los Datos
Comenzamos creando una copia de nuestro conjunto de datos y eliminando las filas con entradas NaN, ya que el coeficiente de correlación no puede calcularse con datos faltantes.
Tumblr media
Luego, procedimos a realizar un diagrama de dispersión de estas variables.
Tumblr media
Observamos que el comportamiento de las variables no es lineal; de hecho, parece más apropiado considerar un ajuste logarítmico para establecer una regresión entre ellas. Este será un tema que exploraremos en futuras entradas del blog.
Resultados del Análisis
Tras la realización del diagrama de dispersión, calculamos el coeficiente de correlación de Pearson.
Tumblr media Tumblr media
El resultado obtenido fue un coeficiente de aproximadamente -0.015 (-0.014984230083466107), con un valor p significativo de 0.022912246058339945.
Además, el coeficiente de determinación asociado fue de 0.0002245271511942507, indicando que una fracción extremadamente baja de la variabilidad del consumo total anual de alcohol puede explicarse por el ingreso total anual.
Conclusión
Este análisis revela una correlación negativa débil entre el ingreso total anual y el consumo total anual estimado de alcohol. Sin embargo, el coeficiente de determinación sugiere que el ingreso total anual es un predictor poco confiable del consumo de alcohol, ya que explica solo una pequeña fracción de la variabilidad observada en los datos.

I'm learning about linear regression so I can learn about gradient descent so I can use texel tuning on my evaluation function. Linear regression sure is satisfying to watch.

Started on linear regression while watching a political debate from my home country. Seeing how bad everything is going right now motivates me harder than anything else at the moment.

D/W Logistic regression vs linear regression
Linear Regression: Linear Regression models the relationship between a dependent variable and one or more independent variables. It's used for predicting continuous values, such as sales or prices.
Logistic Regression: Logistic Regression is used for binary classification problems, estimating the probability that an instance belongs to a particular category. It's common in tasks like spam detection or predicting customer purchases.
