Much depends on how well-formed and un-formatted the table is. Take this

One such dataset, called levitus, holds sea surface temperature and salinity (SST and SSS), based on the 2013 version of the World Ocean Atlas.

R, Python, and SAS: Getting Started with Linear Regression

Consider the linear regression model, $$ y_i=f_i(boldsymbol{x}|boldsymbol{beta})+varepsilon_i, $$ where $y_i$ is the response or the dependent variable at the $i$th case, $i=1,cdots, N$ and the predictor or the independent variable is the $boldsymbol{x}$ term defined in the mean function $f_i(boldsymbol{x}|boldsymbol{beta})$. For simplicity, consider the following simple linear regression (SLR) model, $$ y_i=beta_0+beta_1x_i+varepsilon_i. $$ To obtain the (best) estimate...
