Chapter 10: Statistics & Regression Calculations 06 Rg_x4 Rg_x4 (list name for x, list name for y [, frequency list] [, equation name to store]) Finds the regression curve using the fourth degree polynomial. (quadratic regression) Formula: y = ax4 + bx3 + cx2 + dx + e Parameters: a, b, c, d, e, R2 07 Rg_ln Rg_ln (list name for x, list name for y [, frequency list] [, equation name to store]) Finds the regression curve using the natural logarithm. (natural logarithm regression) Formula: y = a + b ln x Parameters: a, b, r, r2 08 Rg_log Rg_log (list name for x, list name for y [, frequency list] [, equation name to store]) Finds the regression curve using the common logarithm. (common logarithm regression) Formula: y = a + b log x Parameters: a, b, r, r2 09 Rg_abx Rg_abx (list name for x, list name for y [, frequency list] [, equation name to store]) Finds the regression curve using the exponential function. (exponential regression) Formula: y = abx Parameters: a, b, r, r2 10 Rg_aebx Rg_aebx (list name for x, list name for y [, frequency list] [, equation name to store]) Finds the regression curve using the Euler exponential function. (Euler exponential regression) Formula: y = ae^bx Parameters: a, b, r, r2 161
