Interpret coefficient of determination (R2)

interpret_r2(r2, rules = "cohen1988")

Arguments

r2

Value or vector of R2 values.

rules

Can be "cohen1988" (default), "falk1992", "chin1998", "hair2011", or custom set of rules()].

Rules

For Linear Regression

  • Cohen (1988) ("cohen1988"; default)

    • R2 < 0.02 - Very weak

    • 0.02 <= R2 < 0.13 - Weak

    • 0.13 <= R2 < 0.26 - Moderate

    • R2 >= 0.26 - Substantial

  • Falk & Miller (1992) ("falk1992")

    • R2 < 0.1 - Negligible

    • R2 >= 0.1 - Adequate

For PLS / SEM R-Squared of latent variables

  • Chin, W. W. (1998) ("chin1998")

    • R2 < 0.19 - Very weak

    • 0.19 <= R2 < 0.33 - Weak

    • 0.33 <= R2 < 0.67 - Moderate

    • R2 >= 0.67 - Substantial

  • Hair et al. (2011) ("hair2011")

    • R2 < 0.25 - Very weak

    • 0.25 <= R2 < 0.50 - Weak

    • 0.50 <= R2 < 0.75 - Moderate

    • R2 >= 0.75 - Substantial
