This free online software (calculator) computes a series of graphical tools for the purpose of Explorative Data Analysis. If we consider the model

response = constant + beta * explanatory variable + random component

then the following assumptions can be tested by the use of this software module:

  • are the data autocorrelated? (The model assumes no autocorrelation)
  • is the random component generated by a fixed distribution? (The model assumes a fixed distribution)
  • is the deterministic component constant? (The model assumes that the distribution has a fixed location)
  • does the random component have a fixed variation? (The model assumes a distribution with fixed variation)

Enter (or paste) your data delimited by hard returns.
