This function plots a simple t-distribution or a t-distribution with shaded areas that indicate at which t-value a significant p-level is reached.
dist_t(t = NULL, deg.f = NULL, p = NULL, xmax = NULL, geom.colors = NULL, geom.alpha = 0.7)
t | Numeric, optional. If specified, a t-distribution with |
---|---|
deg.f | Numeric. The degrees of freedom for the t-distribution. Needs to be specified. |
p | Numeric, optional. If specified, a t-distribution with |
xmax | Numeric, optional. Specifies the maximum x-axis-value. If not specified, the x-axis ranges to a value where a p-level of 0.00001 is reached. |
geom.colors | user defined color for geoms. See 'Details' in |
geom.alpha | Specifies the alpha-level of the shaded area. Default is 0.7, range between 0 to 1. |
# a simple t-distribution # for 6 degrees of freedom dist_t(deg.f = 6)# a t-distribution for 6 degrees of freedom, # and a shaded area starting at t-value of one. # With a df of 6, a t-value of 1.94 would be "significant". dist_t(t = 1, deg.f = 6)# a t-distribution for 6 degrees of freedom, # and a shaded area starting at p-level of 0.4 # (t-value of about 0.26). dist_t(p = 0.4, deg.f = 6)
