This free online software (calculator) computes the Simple Linear Regression model (Y = a + b X) and various diagnostic tools from the perspective of Explorative Data Analysis. Note that the lagplot of X and the Autocorrelation Function only make sense when working with time series. All other diagnostics (scatterplots, histogram, kernel density, and QQ normality plot) can be used for data series with or without time dimension.
