Analysis: Regression analysis by orthogonal polynomials for double factorial scheme with additional control

Description

Regression analysis by orthogonal polynomials for double factorial scheme with additional control. Cases in which the additional belongs to the regression curve, being common to the qualitative levels. In these cases, the additional (usually dose 0/control treatment) is not part of the factor arrangement. One option addressed by this function is to analyze a priori as a double factorial scheme with an additional one and correct the information a posteriore using information from the initial analysis, such as the degree of freedom and the sum of squares of the residue.

Usage

desd_fat2_quant_ad(output, ad.value = 0, design = "FAT2DIC.ad", grau = 1)

Arguments

output	Output from a FAT2DIC.ad or FAT2DBC.ad function
ad.value	Additional treatment quantitative factor level
design	Type of experimental project (FAT2DIC.ad or FAT2DBC.ad)
grau	Degree of the polynomial (only for the isolated effect of the quantitative factor)
